Definitions
- the invention relates to a method and system for integrated assessment, coding and scoring of overall health and, more specifically, at times when communication and decision-making are particularly crucial such as in the assessment of perioperative risk.
- perioperative risk be interpreted as being influenced by two major components: the patient's physical status and the planned surgical invasiveness.
- Lema M J Using the ASA Physical Status classification may be a risky business, ASA Newsletter 2002; 66(9).
- ASA American Society of Anesthesiologists
- PS Physical Status
- the ASA PS score does not distinguish between disorders of different systems or the nature of different disorders within the same system. Rather, it provides a single number to represent the systemic severity of the patient's overall medical condition. Hence, a given score does not guide preparation for a patient with asthma vs. renal disease vs. cardiac disease vs. metastatic malignancy. Moreover, it does not delineate or cumulate risk based upon multiple disorders. This has prompted the inventor to hypothesize that, with respect to the ASA score, the whole is less than the sum of its parts. In a recent assessment of 220 patients that underwent preoperative assessment under my supervision at a tertiary care medical center and received an ASA physical status score of 3 (significant systemic condition), or 4 (life-threatening systemic condition):
- the development of risk stratification indices also has been popular.
- these systems which include the Charlson Comorbidity index, Mortality Probability Model and APACHE score, focus on disorders with high morbidity and mortality that do not necessarily pose as high a risk as other conditions in the acute perioperative period.
- the Charlson index provides scores of 1 and 6 for prior myocardial infarction (a finding that significantly increases the risk of an adverse cardiac event in the perioperative) and metastatic malignancy, respectively Scales D C, Laupacis A, Pronovost P J, A systematic review of the Charlson comorbidity index using Canadian administrative databases: a perspective on risk adjustment in critical care research , Journal of Critical Care 2005; 20(1):12-19. (As will be shown later, the indices have little in common with the major components of the present invention.
- Scoring systems have also been described for specific disorders.
- the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure classifies three stages of hypertension: prehypertension (systolic 120-139 mmHg, diastolic 80-89 mmHg), Stage 1 (systolic 140-159 mmHg, diastolic 90-99 mmHg), and Stage 2 (systolic>160 mmHg, diastolic>100 mmHg) in light of the direct relationship between elevated blood pressure and risk of morbidity.
- the New York Heart Association defines four classes of heart failure based on degree of physical limitation—from no limitation (Class I) to incapacitation (Class IV).
- Noncardiac disorders examples exist for noncardiac disorders as well.
- the Child-Pugh score provides a means to grade the severity of liver disease based on clinical symptoms and laboratory data; and five stages of renal dysfunction have been delineated by the National Kidney Foundation based on glomerular filtration rate.
- Other rating systems integrate signs and symptoms to generate qualitative gradations by which the severity of the condition and the adequacy of therapeutic management are judged.
- diabetes control is evaluated based on glycosylated hemoglobin, insulin requirements, blood glucose readings before and after meals, tendency for harmful extremes, and end-organ injury. Scoring of asthma severity is based on frequency and severity of symptoms and inhaler use.
- ASA physical status classifications a study of consistency of ratings , Anesthesiology 1978; 49(4):239-43; Ranta S, Hynynen M, Tammisto T, A survey of the ASA physical status classification: significant variation in allocation among Finnish anaesthesiologists , Acta Anaesthesiol Scand 1997; 41(5):629-32. Nonetheless, there are several reasons why, despite its shortcomings, the ASA PS system has endured. First, it can be determined based on information obtained from a history and physical examination without the need for additional data. Second, its five-point scoring system is intuitive and easy to remember. In addition, unlike other illness severity scoring tools, the ASA PS was designed to be applied to patients of all ages, medical conditions, and degrees of health.
- the ASA PS was intended to reflect the condition of an individual irrespective of the planned surgical procedure.
- the ability to assess perioperative risk is limited.
- the need for a system by which to classify surgical severity was recognized; and several surgical risk scoring systems have been proposed.

- the John Hopkins Risk Classification System employs a five-level classification based on location and extent of surgery, anticipated blood loss and fluid shift, postoperative anatomic and physiological alterations and the need for postoperative intensive care monitoring. Of note, the 3-tiered ACC/AHA and 5-tiered Pasternak rankings are not interchangeable.

- issues potentially critical to anesthesia management include conditions such as prior halothane hepatitis or porphyria (a disorder of blood cell enzymes); communication problems; emergency surgery; presence of an AICD (automatic intra-cardiac defibrillator); latex allergy; risk of malignant hyperthermia; morbid obesity; pregnancy; and potential for signs and symptoms of acute withdrawal.

- latex allergy risk of malignant hyperthermia
- morbid obesity morbid obesity
- pregnancy potential for signs and symptoms of acute withdrawal.
- emergency surgery which is designated with an “E” after the numeric score to indicate that there may not be time to optimize the patient's condition preoperatively (a factor that results in a higher level of reimbursement).

Chin T: Avoiding EMR meltdown: How to get your money's worth.
- the problem (which is not limited to the perioperative period) is that the disparate nature of terminology, classification, coding and scoring has been allowed to metastasize, with disparate systems for clinical evaluation, special testing, decision making, communication, resource allocation, quality assurance and research applications. To date, problems in these areas have been addressed with band aids or by trying to adapt programs designed to solve a different problem.
- This invention cures these problems treats the underlying “illness” by introducing a new mechanism for data entry, coding and scoring and a mechanism to enable universality among clinical, communicative, administrative and investigative components.
- the seamless integration of data is enabled with little or no added burden to the clinician in that main impact of the invention is on the information after it has been accrued by the patient's healthcare providers.

- 11 may be greater on a system other than that with the underlying surgical pathology—e.g., RESP after an large abdominal incision) and the nature and severity of comorbidities (problems not directly related to the planned procedure but which may impact significantly on the patient's ability to withstand the demands of a procedure such as invasive surgery or the need for/effectiveness of additional diagnosis and therapy.
- RESP after an large abdominal incision
- comorbidities problems not directly related to the planned procedure but which may impact significantly on the patient's ability to withstand the demands of a procedure such as invasive surgery or the need for/effectiveness of additional diagnosis and therapy.
- the lack of a uniform language and code is evident at a major institution about which the author is very familiar.
- the operating room scheduling system captures the CPT code and anesthesiologists bill according to Relative Value Units, which are based upon CPT codes; but many surgical offices use the ICD-9 disease code, the NSQIP quality assurance program uses specified text entries (or their equivalent), government-mandated Surgical Care Improvement Program (SCIP) measures rely upon ICD-9 codes, and hospital billing has relied upon ICD-9 procedure codes (and a system for crosswalk to establish compatible codes).
- Each coding system has its coding specialists.
- the present invention provides such a system and method for assessment, quantification and communication and then details a preferred embodiment and adaptations thereof. While the embodiments detailed herein focus primarily on integrated preoperative assessment, it is within the spirit and scope of this invention to focus on and adapt individual components for assessment in other contexts such as longterm care and management in other acute (e.g., emergency, battlefield, or intensive care) settings as well as for triaging and transferring care among healthcare providers in those contexts. Likewise, a patient may followed at standard intervals during long-term care, with additional assessments as deemed indicated, and with more frequent serial assessments during acute challenges or initiations of new therapies. As detailed later in this disclosure, score-driven communication not only would be of great value for perioperative healthcare providers but at virtually every exchange of information among healthcare providers and between healthcare providers and their patients.

- the physical condition of the patient is identified by the ASA PS of medical condition (which is modified in a unique system-specific basis in more elaborate embodiments in accordance with the spirit of the present disclosure) and the expected degree of surgical invasiveness is provided by an integration of the aforementioned ACC/AHA classification of surgical risk and the Johns Hopkins classification of surgical invasiveness (which is modified in a unique system-specific basis in more elaborate embodiments in accordance with preferred applications of the present system).
- the present system offers a methodology with the simplicity of ASA PS 1-5 ranking that will serve clinical, investigative and administrative functions—useful to the clinician developing a plan for perioperative care, to the investigator seeking data for outcomes research and evidence-based guidelines, and to the administrator developing operating room case schedules as well quality assurance, productivity assessments and billing policies.
- This has led to the present integrative mechanism of quantitative assessment and communication which is disclosed and referenced herein under the acronym “SHAPETM” (Silverman-Holt Aggregate Preoperative Evaluation and, for more general applications, Silverman-Holt Aggregate Patient Evaluation).
- SHAPETM provides a mechanism for communicating and displaying vital information (see FIGS. 3-6 ).
- ASPIRINTM ASA physical status, Surgical risk/invasiveness, Physical factors primarily affecting ventilation, Intubation predictors, Risk Indicators that identify items of potential anesthesia-related concern
- ASPIRINTM can be easily expanded so that the last two letters relate Interim Information & Issues, (Information and issues pending, as well as information which may have arrived since the original note was completed or last updated) and Needs that should be addressed (e.g., equipment, missing information, need for special medications such as preoperative antibiotics) (see FIGS. 3-7 ).
- ASPIRINTM integrates varied characteristics that may otherwise be unrelated to one another (as opposed to aspects of a given condition) and that themselves may be integrative assessments as opposed to an objective measurement.
- ASPIRINTM also may be changed to ASPIRINGTM, wherein the “G” stands for gas and thereby relates the anesthesia plan.
- the SHAPETM scores simply can be displayed ( FIGS. 3-7 ) and/or integrated to generate patient condition and surgical invasiveness sums, products or other arithmetic functions, with derived indices, including, for example, those detailed herein (lower portion of FIG. 3 ).
- FIGS. 3-7 The details and applications of the present system and method are presented below. Its advantages have been summarized in Table 2 and are detailed throughout the present disclosure.
- Integrative assessments of different comparably coded and scored components of the SHAPE TM database Generation of score-driven summary and communication tools such as the ASPIRIN TM display, wallet card, healthcare provider-to-healthcare provider sign-out summary Options for cumulative and integrative scoring of comparably scored multiple features, multiple body systems, multiple components of the SHAPE TM database, Score-driven processes based upon single, multiple, cumulative and integrated components of the inventive database: Grouping items by score and, when indicated, scoring cutoffs Displaying items by score and, when indicated, scoring cutoffs Exporting items by score and, when indicated, scoring cutoffs Text-and score-driven/cutoff-driven co-population for other applications. Generation of integrated score-driven scripts.
- Score-driven patient transitions/disposition Home without special care Home with special at-home care Extended care facility Level 1 trauma center Intensive care unit Step-down unit
- Score-driven triaging to see anesthesiologist prior to day of surgery preop evaluation by PCP specialty consultation and/or special testing by a PCP
- Score-driven scripts for diagnostic testing General laboratory testing Specific testing Specific score-driven treatment and management algorithms
- Score-driven scripts for level of patient management Management of patients with overall morbidity scores Managements of patients with scores for specific body systems (e.g., cardiac score justifying possible use of beta-blocker therapy)
- SCIP Surgical Care Improvement Project
- SHAPE TM provides the classification, uniformity, and potential multi-purpose integration that are not provided by other methods) Scored assessments of interim and final outcomes Scored assessments of test results, thereby minimizing subjectivity in interpretation of clinical significance (e.g. of NSST on EKG as described in text). Hemodynamic Indices Status at discharge Score-driven communication and displays Research and the accrual of data for evidence-based guidelines: Classification, coding and scored stratification for outcomes research provide the detailed databases required for generation of meaningful data for documentation of perioperative morbidity, assessment of interventions, and generation of evidence-based recommendations. Links to comparably coded information sources (e.g., textbooks) —based on identical text and code as well as comparable text and code (as mediated via the text, code and score conversion dictionary).
- coded information sources e.g., textbooks
- FIG. 6 shows some of the information that may be available and accessible.
- a preferred embodiment entails the provision of progressive specificity. For example, this may be achieved by a listing of positive body systems (with scores in descending order); identification of positive aspects of the body system by clicking on the given body system; or jumps to sections of the display (or other aspects of the program) co-populated with the given feature
- SHAPETM enables their selection and storage with a 1.5 score—without the need to complicate the SHAPETM ASPIRINTM display or clinical SHAPETM indices (i.e., simply consider them a “1” for display purposes)
- the SHAPETM text, code and inventive score can be applied to chronic as well as acute conditions and local as well as systemic effects.
- the embodiments described below will focus on systemic effects in the (acute) perioperative period.
- ASA Physical Status Because of its time-tested clinical utility, the ASA PS classification system has been chosen for use as the foundation for the present SHAPETM representation of patient condition. However, in order to provide additional depth of information, while not forsaking its simple elegance, the present invention introduces the practice of assigning a 1 to 5 (or 0 to 5) severity score for each major organ system based on information learned from the patient history and physical examination and associated testing. The inventive system further provides the methods and algorithms to do so, thereby generating what is termed herein SHAPETM Individual Systems Status (SISSTM or SISTM) scores (Table 3 and FIG. 32 ).
- SISSTM or SISTM SHAPETM Individual Systems Status
- the scoring criteria for each body system parallel the overall ASA PS classification but, by being body system-specific, are uniquely different and enable quantification of the ability of the given body system (for example, cardiac or respiratory) to withstand potential surgery-induced demands and insults—what is referred to herein as a SHAPETM assessment of resilience.
- a user may simply score his/her entries of data for each body system—in accordance with the partial display of scored features and subfeatures that are included in FIG. 32 —during the history and physical examination.
- items such as those in FIG. 32 may be hard-coded along with their score for selection by the user—when possible without compromising simplicity, scoring is based upon entries at the feature or subfeature level. This may entail a listing of scored features and subfeatures as in FIG. 32 .
- the details of the branched-chain logic that is employed in preferred embodiments is shown in FIGS. 8A-C and 9 A-C and discussed and disclosed later in this document.
- each item in FIG. 32 and delineated in FIGS. 32.1 and 32 . 2 is based on branched chain consisting proximally of system, subsystem and feature category codes.
- scoring for each body system e.g., Central Nervous System, Cardiac System
- the SHAPETM methodology is implemented so that scorable choices (e.g., features and/or subfeatures) generate the proximal (e.g., system) score.
- Options for arranging items are summarized as follows: 1) Grouping features within each body system or subsystem or feature category according to their default score (with an option to change that score for a given feature in a given patient) as shown in tabular form in FIG. 32 and as listed on user screens (Tables 12, 13, 14 and 16) which are described later in this document; 2) Grouping by any number of alternative means within a system, subsystem or feature category, including sequence of questioning while obtaining a history and sequential order of questions in a questionnaire. 3) Grouping of signs and symptoms based on clinical patterns. 4) Simply listing items in alphabetical order or in numerical sequence based on their respective codes. Again, scoring accompanies item selection as may be facilitated by providing a default score and the option to change a score for each individual item.
- Item co-populates multiple portions (e.g., multiple bodily systems) of the H&P and data base
- Item co-populates algorithms for communication, diagnostic and treatment algorithms, quality assurance and quality improvement data bases, etc. based on: Identical terminology Common terminology based on universal language (as mediated by the text, code and score conversion index and dictionary) Common significance based upon text and/or code + score (as mediated by the text, code and score conversion index and dictionary)
- drop-down menu which may include: Details of more proximal branch logic Default text that will appear in note (may be more detailed than simply what is stated for the feature or subfeature) List potential sites of co-population within the SHAPE TM database for the given item (i.e., other sites where the hard-coded choice appears —see text for discussion of this issue).
- the present invention enables that, for patients with conditions that warrant an ASA PS ⁇ 3, a code (for example, first letter or first few letters of the given system) be superscripted to the traditional ASA PS score to indicate the affected organ body system(s).
- a code for example, first letter or first few letters of the given system
- ASA 3 CARD for Cardiac
- a patient with long-standing insulin-dependent diabetes mellitus would receive an ASA 3 ENDO (for Endocrine).
- ASA 3 CARD,ENDO a patient with exertional angina and insulin-dependent diabetes
- the numerical score(s) that is (are) represented simply could be the system(s) with the highest score.
- ASA4 CARD>ENDO or ASA 4 CARD 3 ENDO could be used to designate both the ASA 4 and the ASA 3 disorders. Comparable annotation is shown in FIG.
- FIGS. 6 and 7 show examples of a potential ASPIRINTM display, which demonstrate some of the increased information (vs. traditional listings on an operating room schedule) that may be generated and used for co-population of other portions of the inventive program or exported for other applications. It would be within the spirit and scope of this invention to have other mechanisms of #-systems display (e.g., systems in parentheses as opposed to as superscripts) as well as to list the systems followed by their score. For purposes of a consolidated meaningful display, it is believed that the illustrated embodiments are most effective.
- ASA physical status score looks at the overall ASA physical status score as being derived from the scores assigned to individual body systems (with the potential to override this score). These in turn are based upon the highest score(s) assigned to signs, symptoms and/or test results within the given body system (SISSTM), typically at the feature or subfeature level. This constitutes a preferred embodiment; however, other means of consistent assignment and management of scores are within the spirit and scope of this invention.
- FIGS. 8C and 9C The embodiment of Table 6 is shown in FIGS. 8C and 9C .
- Alternative embodiments, relying on equivalent S, sS, FC, F, sF, and D progression are shown in FIGS. 8A , 8 B, 9 A and 9 B.
- a sample step-by-step process for data entry in accordance with this branched-logic mechanism is detailed later in this disclosure with reference to FIGS. 26-31 .
- the present invention also facilitates uniquely consistent and universal coding for exporting to and integration with other databases.
- a key advantage of the present invention is that it accomplishes the coding and scoring without “getting in the way.”
- the carefully configured branched logic further allows such processes to be relatively seamless and transparent.
- the text, code and score conversion index and dictionary allows for automated translation and universality. Instead of requiring repetitive progression down each branch, the present invention provides for default jumps (if a body system is negative) and provides options that obviate the need for user delineation of S/sS/FC/F/sF . . . .
- FIGS. 32.1 and 32 are examples of what some might consider all systems and subsystems—configured to enable options for each subsystem to be viewed on a single screen—is shown in FIG. 32 .
- FIGS. 32.1 and 32 are examples of what some might consider all systems and subsystems—configured to enable options for each
- FIG. 32 does not distinguish between F and sF (since they are coded and scored comparably). Items are worded to be user friendly and may actually represent more than one F or F+sF; this would be evident in storage within the database and thereby enable searches based on individual as well as combined features and subfeatures.
- the user may also elect to select the information provided by a feature but to bypass the prompt to assign the default score or to select a score. That is, the user may select the item without its score.
- This may offer the advantage of allowing for a more speedy entry of data, in that once the feature with the highest score is selected for a given body system or subsystem, other choices could be selected without concern about scoring.
- the detailed scoring capabilities of the present invention provide for greater detail, greater consistency, and more robust population of the SHAPETM database and co-population of other sites (e.g., when data are exported to diagnostic and treatment algorithms and related scripts). Furthermore, unless one changes the default scoring (because of his/her clinical findings), the process of scoring is transparent.
- the system-based scoring for each of the body's main systems is done in large part not only to ensure communication consistent with (and superior to) the basic ASA physical status score described above, but also to take into account that without consolidation into a body system or subsystem score, the range of individually scored features and subfeatures would be unmanageable (perhaps accounting for why, to the best of my knowledge, heretofore no one has been able to effectively design a highly detailed, integrative system such as that described herein). Borrowing from an old beer commercial, one might say above SISSTM—“better accuracy” and “less filling.”
- Scores for S, sS, FC, F and sF are represented by $# (as shown in FIGS. 8 and 9 and throughout this disclosure. Descriptors are unique—they provide valuable information but do not significantly affect the severity of the disorder; hence they are not scored. To facilitate their inclusion in the database and accommodate preferences for description terms and expressions, Descriptor codes may be grouped as shown in Table 7.
- the body system-specific scoring introduced herein looks at the overall ASA physical status score as being derived from the scores assigned to individual body systems (with the potential to override this score). These in turn are based upon the highest score(s) assigned to signs, symptoms and/or test results within the given body system (SISSTM), typically at the feature or subfeature level. This constitutes a preferred embodiment; however, other mechanisms of consistent assignment and management of scores are within the spirit and scope of this invention.
- scored features or subfeatures are within a feature category of a given subsystem, which is, in turn, a part of a body system (such as CARDIAC).
- Co-population and exporting may be at any of the aforementioned levels of branching.
- FC/F/sF (and possibly D) code remains fixed while the S/sS portion of the code changes (as shown in Table 6).
- body systems and subsystems should not be considered absolute or restrictive when applied to the present invention; but once a decision is made it should be maintained so as to ensure consistent coding.
- diabetes is coded as subsystem and treated as such in applications of the program (e.g., co-population and exporting).
- the SISSTM scoring permits cumulative scoring based upon the number of disorders (as may be ascertained from the number of positive feature categories) or diseased body systems and their degree of dysfunction in what is called herein the SHAPETM Aggregate Disorders (SADTM) score ( FIG. 3 ).
- the provisions for integrated details afforded by the present invention uniquely enable one to overcome the problem of introducing excessive subjectivity and potential bias when viewing findings in the context of other conditions and risk factors.
- nonspecific ST-T (NSST) wave changes on an EKG likely would be dismissed as not clinically significant in an otherwise healthy individual without significant risk factors for coronary artery disease.
- the present invention offers potential ways for a healthcare provider or institution to address this issue:
- multiple body systems with the same score may be identified at the end of the History and Physical ( FIG. 4 ) or as by superscripts in the ASPIRINTM display ( FIGS. 6 , 7 B, and 7 C).
- the present invention enables assignment of an incremental value to the “modified ASA score” when there are multiple body systems that warrant a given score. For example, if both cardiac and respiratory systems were scored 3, then one could assign a cumulative score of 3.2 or 32 (in accordance with a preferred embodiment, the decimal or superscript has been elected to reflect the number of body systems). If three body systems were scored 3, this could be represented as 3.3 or 33.
- An alternative embodiment entails adding 0.2 for each additional ASA 4 body system and 0.1 for each additional ASA 3 body system.
- a formula i.e., a correction factor
- An alternative embodiment for scoring (regardless of the number of body systems entails conversion of the ordinal 1-5 scores to points which are reflective of relative illness and impact. For example, based on analyses of data from the initial applications (described above), preferred embodiments will enable 1-5 scores to be converted to points that take into account the dramatic rises in morbidity, length of stays and costs at greater degrees of illness (e.g., 2 ⁇ 2, 3 ⁇ 7, and 4 ⁇ 25 points). Comparable points may be assigned to the 1-5 surgical scores.
- scores of 3 for CARD and ENDO could provide a variety of SADTM scoring options including: 6 (simple addition), 3.2 (modified for multiple systems), 14 (addition of 7+7 points), 7.6 (points modified for multiple systems).
- the present invention is also designed to address two related vital issues—what to when a disorder of one body system also affects another body system or when more than one system is affected by a “Multisystem” condition. Ways in which this is accomplished by the present invention include:
- SHAPETM provides the following:
- the invention provides a mechanism for designating scores for each of the body systems associated with a given feature or subfeature. Where two or more specific body systems are involved, unless otherwise specified by the user (see below), overlapping information would impact on the score of each system and both would be included in an inventive cumulative score, such as, SADTM. Examples of such interactions include:
- Multisystem disorders present particularly challenges in that they do not necessarily have their own body “system.”
- the Multisystem paradigms can be accessed by the following means:
- Table 9 includes a prompt to define a “Weighting Code (vs. Multisystem Disorder) for each body system affected by the Multiystem Disorder. This addresses a major issue that otherwise can plague a data entry program.
- vs. Multisystem Disorder vs. Multisystem Disorder
- This addresses a major issue that otherwise can plague a data entry program.
- a specific body system e.g. “Cardiac”
- a multisystem condition e.g., “Amyloidosis”
- SHAPETM SHAPETM's text, code and inventive score can be applied to the impact of a variety of challenges and interventions, including surgery, trauma, and therapies. Consistent with the focus on embodiments addressing perioperative concerns, the embodiments described below will focus on the impact of surgery.
- Surgical Risk & Invasiveness To be consistent with the 5-point ASA PS system, a five tiered classification scheme is used for ranking of surgical risk and invasiveness (or SHAPETM Overall Cutting Upset (SOCUTM)) as identified in the second letter in ASPIRINTM (S) as described above in accordance with the present invention (See Table 10a).
- SOCUTM Overall Cutting Upset
- S ASPIRINTM
- the lowest risk score of 1 would be appropriate for superficial procedures such as a breast biopsy which may require minimal sedation (comparable to the “low-risk” classifications of the ACC/AHA Guidelines and the “minimally invasive” class of Pasternak rankings).
- a score of 5 is assigned to highly invasive intrathoracic and intracranial procedures, those associated with massive blood loss (>1500 mL) as well as any emergent major operation (consistent with the ACC/AHA Guidelines “high-risk” classification and Pasternak's most invasive category). Scores of 2 through 4 represent the spectrum of risk between these two extremes. Since it has been concluded that the “intermediate” ranking of the ACC/AHA was too broad, it has been subdivided, in accordance with a preferred embodiment of the present invention, in accordance with the surgical invasiveness score proposed by Pasternak as well as by taking into consideration anesthetic requirements and the potential for otherwise unsuspected pulmonary or hemodynamic changes.
- the score proposed by Pasternak is not consistently translatable to the low, intermediate- and high-risk ACC/AHA classifications and thus not readily applicable to established risk assessment indices and therapeutic guidelines, which include the ACC/AHA classification as to when consultation with a cardiologist is indicated prior to surgery.
- the 1-5 score of overall surgical risk and invasiveness (referred to as the SHAPETM Overall Cutting Upset or SOCUTM [pronounced “sock you”] score) introduced herein is designed to provide greater precision and greater relevance to perioperative events than the ACC/AHA classifications, while maintaining compatibility with indices and guidelines that utilize the ACC/AHA classifications.
- Another unique inventive feature is the body system-specific coding and scoring of the surgical risk/invasiveness score in a manner comparable to that for the inventive SISSTM score of patient condition.
- the inventive SHAPETM Intersystem Cutting Upset (SICUTM) score is employed in accordance with the present invention to delineate the inter-system impact of the planned surgical procedure regardless of the patient's underlying condition (DIFF).
- DIFF patient's underlying condition
- SICUTM scoring is provided in Table 10b and shown in FIGS. 6B and 7C .
- the SICUTM score is based on the potential upset of each body system's role in maintaining overall patient condition (i.e., its overall systemic effect).
- a vital body system such as Respiratory may receive a higher SICUTM score than the body system actually undergoing the given surgery; e.g., if a large incision is required to removal an intraabdominal mass and there is subsequent pain and compromised breathing.
- kidneys from someone who already requires dialysis may receive a lower KUBU (kidney, ureter, bladder, and urethra) score than less extreme renal surgery on someone whose kidneys still are functional (since the change from normal function to decreased function in the latter is of greater systemic impact).
- KUBU kidney, ureter, bladder, and urethra
- a patient with a sarcoma of the leg may be assigned a higher score for systemic impact than an individual who underwent amputation and has remained tumor-free.
- the inventive system can be modified to score local as well as systemic impacts of an intervention such as surgery. In which case, SICUTM score likely would be higher at the site of the surgery.
- Free flap AV fistula- Ventriculo-peritoneal shunt . Feeding Tube. ORIF (not femur or hip).
- ICDL 3 INTERMEDIATE Straightforward Head and Neck surgery (functional neck dissection, extensive Moderately invasive, EBL 500-1500 ml thyroid). Limited Intraperitoneal (open cholecystectomy, hysterectomy, simple nephrectomy, colectomy, prostatectomy). Late D&E*. Routine Spine (laminectomy, fusion). Hip or femur fx. Major Arthroplasty (knee/hip/shoulder). Extensive Endoscopic procedure (gastric bypass, Nissen fundoplication*). Splenectomy.
- Procedures that consistently are amenable to local and/or conscious sedation have been annotated with an “L,” in that they likely would not be influenced by anesthesia-related factors such as a difficult airway.
- anesthesia-related factors such as a difficult airway.
- certain procedures are associated with features that may disproportionately influence their effects on outcome variables such as length of stay and total hospital costs independent of surgical risk/invasiveness; examples, which have been annotated with a “ ,” include those requiring postoperative intravenous antibiotics because of hardware insertion or prolonged observation to ensure flap viability, surgical effectiveness, or device functioning. In such cases, the effect of coexisting morbidities on length of stay and costs may need to take into account obligatory lengths of stay.
- SHAPE TM Itemized Cutting Upset (SICU TM) Score. Surgical Procedure (with SOCU TM score in parentheses). Selected surgical procedures are scored w/ and w/o epidural for improved SHAPE TM Itemized Cutting Upset (SICU TM) Score for upset by surgery postoperative (on given system's role in maintaining overall patient condition) is ⁇ 2* analgesia.
- CNS CNSischemia ENDOCRINE ENDOdiabetes CARDIAC & BP CARDischemia

- Selected surgical procedures are scored w/ and w/o epidural for improved SHAPE TM Itemized Cutting Upset (SICU TM) Score for upset by surgery postoperative (on given system's role in maintaining overall patient condition) is ⁇ 2* analgesia.
- Selected surgical procedures are scored w/ and w/o epidural for improved SHAPE TM Itemized Cutting Upset (SICU TM) Score for upset by surgery postoperative (on given system's role in maintaining overall patient condition) is ⁇ 2* analgesia.
- a key feature of the present invention is that it accomplishes this with its unique foundation of itemized scoring—a potential enormous gain for relatively little user effort that does not entail retrospective assessments of variables and assignments of scores.
- SHAPETM SHAPETM's text, code and inventive score also can be applied to items which, often because of the given context (e.g., perioperative), constitute a risk or management issue that is disproportionate to—or not reflected by—their “A” or “S” score.
- the literature is replete with recommendations, some of which are evidence-based, as to how to characterize, plan for and manage what may be termed “non-ASA score, non-surgical invasiveness factors” that affect anesthetic complexity and potentially impact of patient morbidity.
- R disk indicators
- ASPIRINTM may generate score-driven communication, preparation and planning based upon an item-specific score or a generalized cutoff (e.g., ⁇ 3).
- assigning a five-point scale maintains the consistency of the scoring system for patient condition (modified ASA class) and surgical risk (modified ACC/AHA class).
- the actual data are stored in the database for subsequent applications as well as to provide greater information to the patient's caregivers.
- scores from each of the five categories are summated score >5 may simply be displayed as a 5. A score of this magnitude should alert the O.R. team to the potential need for special planning.
- Risk Indicators include anesthesia-specific, perioperative-specific, and more general conditions based upon score-driven population of entries such as Allergies, Medications, Prior Anesthetics, Social Habits, Review of System, Physical Exam and Laboratory reports. As detailed in FIG. 11 and shown in portions of FIGS.
- a component of the present invention is a letter/alphanumeric scored code for such issues that may have a condition that is disproportionate to their “A” or “P” or “I” relative score.
- the Risk indicator score that is assigned [SHAPETM Alphanumeric Score for Risk Indicators (SASRITM)] often depends on the context (e.g., it may be higher for pre-anesthetic care than it would be for chronic medical care). Higher scores provide an indication of potential concerns for the clinicians involved with the patient's care and may be accompanied by a score-driven email notice, phone call or page as may be based upon an item-specific score or a generalized cutoff (e.g., ⁇ 3).
- SASRITM is a major improvement over existing systems wherein the perioperative impact of a clinical condition such as malignant hyperthermia, which does not pose a physical limitation on daily life, is underestimated by the ASA physical status score. Hence, without effective communication, an anesthesiologist may not be aware of this issue until he/she reviews the chart prior to initiating the anesthetic. Even when a disorder would otherwise be evident, the score-driven categorization of specific features by SASRITM also is central to the value of the inventive Risk indicators.
- AICD automatic implantable cardiac defibrillator
- FIG. 11 Examples of scoring Risk indicators are shown in FIG. 11 .
- the generic SASRITM scores in FIG. 11 facilitate tabular display but may be supplemented with graded scores that are more specific for a given condition. For example, adverse/allergic reactions to medications may be categorized as:
- the Risk indicator score that is assigned [SHAPETM Alphanumeric Score for Risk Indicators (SASRITM)] often depends on the context (e.g., it may be higher for pre-anesthetic care than it would be for chronic medical care).
- the data shown in FIG. 11 would be stored as Risk indicator/specific grouping/feature category (e.g., alcohol)/scored feature or subfeature.
- Risk indicator/specific grouping/feature category e.g., alcohol
- the feature category/feature/subfeature . . . components of the code remain intact throughout the database.
- the body “system” score assigned for a given item may be different (e.g., higher) for the Risk indicator body “system” than for the body system associated with the original site of data entry; however, in preferred embodiments, the FC/F . . . score remains unchanged. This likewise is maintained for “Interim Information and Issues” as discussed below in greater detail.
- This next component of ASPIRINTM identifies information and issues that likely will be supplemented after completion of the given entry into the database (e.g., after the given history and physical examination). This may be referred to as “IIITM, an adaptation of the common ethnic expression when one realizes something important may be missing (“aye, aye, aye”).
- the inventive system assigns “I” scores to the entries—on a scale comparable to that for A, S, P, I, and R (e.g., the uniform 0-5 code of FIGS. 17 , 18 , 20 , and 21 or specific codes tailored to specific entries).
- a cutoff e.g., ⁇ 2
- the scores may be modified as results are received and actions are taken.
- a preferred mechanism for display under “I” is to group according to score. Scores at or above a certain cutoff may generate an “alert” which could be in the form of an email, page, phone call, or special notation of an available display. This may be time-dependent, e.g., an alert would be generated 24 hours before the scheduled surgery. Depending on the score, it may provide options or mandates.
- an aspect of embodiments of present invention addresses the different requirements for acquiring information and addressing issues among healthcare providers.
- the anesthesiologist would be more interested in obtaining and reviewing a previous anesthetic record; a surgeon might be more interested in tests to assess the spread of a malignancy.
- embodiments may contain subcategories with respect to Interim Information and Issues. A preferred way to populate these subcategories is via the user's code that is entered into a given cell ( FIG. 17 ).
- Each healthcare provider could initially address his/her specific concerns, while still having the opportunity to review the summated issues.
- the “I” section gets repeatedly updated.
- the arrival of new information or the recording of new decisions may populate and co-populate the database in several ways:
- a preferred embodiment includes such a provision for information under “I,” with options to access details (FIG. 6 )—e.g., via a drop-down menu.
- options to access details e.g., via a drop-down menu.
- the SISSTM or SASRITM can be annotated (as with asterisks or with the “I” score). These would automatically be modified in accordance with changes under “I.”
- Needs primarily will be generated by:
- Listings under N can be score-driven in accordance with the options for displaying R and I. N may play a vital role in the mandated “time-out” prior to the onset of surgery. In addition to listing standard components, N could identify critical needs (display of which is score-driven) that should be included a final check (time-out) for the given patient. These could be based on components such as an “antibiotic score,” a score-driven determination of which patients require antibiotics on the morning of surgery
- FIG. 6 i shows a sample array of an electronic data sheet and display that can be utilized on institutional computers, a hand-held PDA or for generation of printouts.
- the full capacity of the system for provision of additional information and links as shown for the ASPIRINTM display above is best achieved with electronic media. Nonetheless, even the printout would be a major advance for patient safety.
- the indications for this are summarized by some of the quotations in Table 1.
- the ASPIRINTM display can be configured so as to readily distinguish the different lettered categories. This automatically is done by the sequence in which they are placed (e.g., A, then S, then P . . . ). However, this may be supplemented with separators such as commas, differences in font, differences in color, or including the specific letter (e.g., A, S, . . . ).
- the goals of the present invention from a patient-care standpoint include facilitating the categorization, scoring and communication of large amounts of information, highlighting potentially high-risk situations, guiding perioperative planning, and providing a mechanism by which to analyze outcomes—with a mechanism that uses analogous coding and scoring for the spectrum of conditions and the gamut of sites for potential co-population.
- FIGS. 7A-C illustrate how the present body system may be applied to provide additional information on an operating room schedule.
- a given case could result in a ASPIRINTM score ranging from “1,1,0,0” to “5 systems , 5 systems , 5,5,5 items 5 item 5 item ,” wherein score-driven superscripted body systems (body system-specific modified ASA and Surgical scores) and items (Risk indications, Interim Information and Issues, and Needs) are determined in relation to established cutoffs; i.e., communication and display of the alphanumeric presentation may be limited to scores of 3 or 4 so as to avoid listing relatively unimportant issues.
- score-driven superscripted body systems body system-specific modified ASA and Surgical scores
- items disk indications, Interim Information and Issues, and Needs
- SHAPETM Inventive Derived Indices Many of these would not have been obtainable prior to the present disclosure of one or more inventive SHAPETM components. Easy calculation, as well as further delineation, may be achieved through the application of a computer-based program for electronic and hard-coded data entry, automated scoring, storage, analysis, and export. This may include any component of SHAPETM as well as imports from other compatible sources.
- the data may be arrayed in columns for integrated assessment, e.g., the SMASHTM (SHAPETM Multifaceted Assessment of Surgical Harm) indices described below.
- SMASHTM SHAPETM Multifaceted Assessment of Surgical Harm
- the drive indications include: triaging for preoperative assessments by an anesthesiologist, primary care physician or consultant (and providing code-compatible justification for such); driving recommendations for laboratory tests; planning intraoperative personnel and resource allocation; implementation of special protocols (for example, for administration of beta-blockers); planning for postoperative intensive care; quality assurance; performance assessments; and investigations.
- DIFF DIFF
- inventive integration and indices include:
- SMASHTM SHAPETM Multifaceted Assessment of Surgical Harm
- the index is constructed so that a higher score indicates a greater degree of overall risk and/or perioperative complexity.
- an inverse function or a low number on the described index would indicate a lesser risk—what may be referred to a greater patient resilience in the context of the anticipated demands of the planned surgery.
- Comparable indices of disorders for nonoperative settings may be used as a mechanism to document illness in a manner comparable to that proposed for the perioperative settings.
- assessments of resilience can be assessed and scored in the context of nonoperative challenges. As noted elsewhere, these may be based on the scores used in the perioperative setting or for “chronic” scores as well as for scores which evaluate local as opposed to systemic impact.
- Airway Index that integrates scores assigned in Tables 11a and 11b.
- the index is termed the SHAPETM Physical factor and Intubation Composite Evaluation (SPICETM).
- SPICETM Physical factor and Intubation Composite Evaluation
- the embodiment also includes a score based on reports of prior intubations, it may be termed the SHAPETM Mask score, Intubation score, and Report score Composite (SMIRCTM).
- SPIRCTM Report score Composite
- These scores may be combined with the other SHAPETM scores and indices described above (e.g., as a component of SMASHTM) to generate new composite indices.
- scored information from a prior intubation may co-populate other portions of the database such as Risk Indicators and may prompt “Need” for special airway equipment.
- SHAPETM provides the inventive tools for an institution to establish cutoffs such as:
- Embodiments such as that shown in FIG. 32 direct the user to features and subfeatures. Alternatively, one could start more proximally in a branch.
- Table 12 illustrates a section of one of several potential arrays for collection, storage and analysis of data in accordance with the spirit of the present invention; a methodology that demonstrates more advanced inventive features in the context of more elaborate branch-chain logic is described later (with reference to FIGS. 26-31 ). In this example and many others, S/sS/FC/F/sF pathways and codes and scores are not shown (since they likewise would be transparent to the user.
- Table 12 and other tables presented herein may be employed as screens of a graphical user interface when the present invention is employed in a computer based system.
- negative indicates that the given body system and its subsystem(s) essentially are within normal limits (no ASA scores of 2, 3, 4 or 5 in traditional 1-5 range).
- Positive means that significant information has been entered into the given body system or subsystem(s). “Positive” may entail a wide range of responses, including any or all of the following effects or meanings:
- Type-in details Type-in more features: b) Sample Screen: Dropdown Menu for Features of Hyperthyroidism Fulminant thyroid storm (5) Poorly controlled hyperthyroidism w/ life-threatening systemic manifestations (4) Symptomatic (nonlife-threatening) hyperthyroidism despite current suppression (3) Stable on current Rx but otherwise would be prone to thyroid storm (3) Current atrial fibrillation (3) Current thyroid-related tachycardia (3) Current thyroid-related hypertension (3) Mild hyperthyroidism well-controlled on medications (2). Type-in details: Type-in more features: Depending on features selected for given program at given institution, SHAPE TM will prevent cummulation of overlapping signs and symptoms as described in text.
- Patient 3 4 ENDOthyr,ENTnarr - to reflect that patient has severe thyroid disorder as well as associated severe airway compromise. Clearly this is providing much more information than a simple score of ASA 4. 4 ENDOtThyr, , ENTmass to reflect that the patient has a severe thyroid disorder as well as current severe airway compromise.
- the SHAPE TM ASPIRIN TM display would be 4 ENDOThyr,ENTmass 3 ENDOThyr #, 55, 5, 0, wherein the 4 indicates the ASA status, the 3# indicatesthe 1-5 score that would be assigned for surgical risk/invasiveness (the superscript adds that the effect of surgery is primarily on the thyroid gland), the “5's” indicate the impact factors impacting on mask ventilation and intubation. and the “0” for the 5 th digit indicates that there were no airway problems with prior anesthetics Clearly this is providing much more information than a simple score of ASA 4.”
- scoring can be generated at the feature and subfeature levels (as opposed to the subsystem, feature category, or descriptor level). Selection of (and/or electronic transfer of) hard-coded features and subfeatures generates a default score (in accordance with the SISSTM score introduced herein). For a hard-coded feature or subfeature, this is the score assigned to the given feature (based on user, institutional, societal, regulatory body and/or national guidelines). For a subsystem, it typically is the highest score assigned to any of the selected hard-coded features of the subsystem or entered by the user by accessing type-in more features and assigning a score to that entry.
- a body system For a body system, it is the highest score assigned to a subsystem within that body system. As within subsystems, there is the option to type-in additional data within a body system—by selecting “other” for that body system, one can type in a new subsystem and features. Note, that although the single highest score likely will be selected for communication with subsequent caregivers, the component scores and cumulative feature score and subsystem scores also will be maintained in the data base.
- the caregiver performing data entry can enter a modified score by assigning a higher or lower value for a feature, body subsystem or system in the given patient.
- This enables a caregiver to make the determination in a given patient that, for example, five class 2 CARD ischemia factors (for example, smoking, hypertension, long-standing NSST changes on EKG, noninsulin-dependent diabetes mellitus, high LDL lipids) may qualify for the CARD system to be rated as a 3.
- This option also may prove helpful if one wishes to record that a patient has improved as a result of therapy (for example, asthmatic improved after being placed on steroids).
- SHAPETM allows for clinical judgment while maintaining a database that retains a feature's base code (regardless of score) and tracks changes in scoring.
- Table 13 shows how features such as those listed in FIG. 32 may relate to the selectable features for the ENDOCRINE system.
- Table 13a illustrates organization of features in terms of similarity of score; other means, such as similarity of features, are also achievable. Instead of checking neg or pos, in the illustrated embodiment, one would simply click on the positive feature.
- the default score is shown in parentheses; a change in score could be accomplished by a variety of potential mechanisms including changing the actual value or entering the score in a “Modified Score” column (or viewing a dropdown menu which lists the default score first) (Table 5).
- type-in add'l info which may not be scored (descriptor), assigned a score by the user or assigned a default score based the scored item with which it is associated.
- hard-coded descriptors may be attainable by a variety of mechanism, including drop-down menus (Table 13b). The program can keep track of these typed-in entries so that they may eventually be incorporated into future versions of the program as hard-coded options.
- the coded and scored entry of type-ins is detailed with preferred embodiments described later (with reference to FIGS. 26-31 ).
- An important aspect of the inventive system is the ability to record information that is deemed important in a preoperative note without concern as to whether listing all aspects of a problem will artificially increase its score. This is most effectively addressed in a preferred embodiment with unscored descriptors described later (with reference to FIGS. 26-31 ).
- the program can automatically prevent the cumulative scoring of overlapping features with item-specific override exclusions algorithm such that, for example, “current atrial fibrillation” and “current thyroid-related tachycardia” can both be listed but would not be additive. Duplicates are handled by the text, code and score conversion dictionary discussed above and illustrated in FIG. 10 . Options for managing multisystem disorders likewise was addressed above and is shown in Table 9. The embodiment illustrated in Table 13 is an example of how to establish a balance between desired detail and unwanted complexity.
- the cumulative score for a body system is the total of all the scores for the subsystems within that body system. However, because of the likelihood for overlap among subsystems, unless indicated otherwise, the score for a body system is based on the highest score assigned to one or more of its subsystems.
- the program may be modified to treat specific subsystems as separate body systems. For example, diabetes may be treated as being independent from the rest of the ENDOCRINE system.
- the overall cumulative score for a patient is the total of the scores assigned to the individual body systems; i.e., the SADTM score (bottom of Tables 12 and 14). However, in most embodiments, to maintain consistency with the standard ASA score for communicative purposes, only the highest scores would be used; e.g., the overall ASA score would be based on the highest system score (e.g., on the 1-5 or newly proposed 0-5 scale). The cumulative scores typically would not be displayed. Either way, they could be stored in a database for quality assurance, billing, and outcome studies and could contribute to the SADTM score.
- Table 14 illustrates storage of the information and scores in a database for three representative patients. For purposes of this presentation, all entries in this example are limited to system Endocrine—subsystem thyroid. However, the total database would include all body systems and other information deemed appropriate in accordance with the present invention. A more detailed database with coding is described later in this disclosure in reference to a preferred embodiment (with its accompanying FIG. 13 ).
- Table 15 shows the logic used for a typical questionnaire, with the provision that the text (and codes and scores) be consistent with SHAPETM if such matching is possible. Issues with respect to interfacing with questionnaires will be discussed with “Imports” later in this disclosure.
- LT Family history of thyroid disease (2) LT >10 lb weight loss prior to onset of therapy (2) LT somnolence prior to onset of thyroid supplementation
- Significant hypothyroidism in need of new or augmented therapy (3) Moderate tracheal deviation (3) Non-life threatening obstructive symptoms when supine (3) Symptomatic hyperthyroidism (nonlife-threatening) despite current suppression (3) Stable on current Rx but otherwise would be prone to thyroid storm (3) Current atrial fibrillation (3) Current thyroid-related tachycardia (3) Current thyroid-related hypertension (3) Current thyroid-related bradycardia (3) Compromised breathing due to severe narrowing or deviation (4). Poorly controlled hyperthyroidism w/ significant systemic manifestations (4) Untreated hypothyroidism w/ significant systemic manifestation (4) Fulminant thyroid storm (5) Myxedema coma (5) Type-in details: Type-in more features:
- Such programs could also provide alternative default scores when longterm as well as acute impact of a disorder is taken into account (described later in this document).
- scores can remain consistent among longterm and acute-perioperative versions if one relies on other aspects of the SHAPETM database (e.g., history of anesthesia-specific halothane hepatitis in Risk Indicators of the ASPIRINTM display) to identify issues that have added impact in the perioperative setting. Either way, the actual challenges could be rated with the SICUTM score or an obvious modification thereof, wherein the lowest score (e.g., 0) would be commensurate with rest.
- the renaming for such purposes is simple: as described, SHAPETM can be translated as Silverman-Holt Aggregate Patient Evaluation (as opposed to Preoperative).
- the present invention is organized to be configured to enable hard-coded choices and type-in options for cross-population (with text, code and score) of different components of the database for a variety of purposes, including: entering information into relevant body systems, arrangement of information for the given preoperative note, storage in databases, identification of special needs, communication, quality assurance, and research. (These are addressed in greater detail in the discussions of co-population and exporting—and their facilitation by a conversion dictionary and interactive index discussed below).
- SHAPETM includes hard-coded options for specific issues that co-populate more than one program location (Some of the multiple options for text, coding and scoring in this context have been discussed above).
- the multiple cross-system components that can be populated in the manner within the SHAPETM database include:
- the present invention also may improve the assessment of laboratory values within NSQIP wherein the lab values are recorded for approximately 13 indices. These can be scored in accordance with a graded scale such as that in FIGS. 17 , 20 and 21 . Again, a score beyond a preset cutoff would determine which values correspond (via universal language and scoring) to abnormal NSQIP criteria.
- data for given body systems may be integrated to provide needed entries (typically at the feature or subfeature level) to co-populate with a common language and score established indices of risk assessment (that, while highly acclaimed, are not universally applied in their current form), diagnosis (e.g., whether to obtain a cardiology evaluation) and treatment (e.g., whether to initiate perioperative cardioprotection with beta-blocking drugs) algorithms.
- Exported entries may be generated from:
- ischemic heart disease may be scored so as to enable distinctions not available from their similar “ischemic heart disease” factor; the simple variable “congestive heart failure” can be graded according to severity as well as to whether it is currently active and the grouping of a wide variety of surgeries as “major” can be improved with the SHAPE 1-5 SOCUTM classification and, more specifically, by the system-specific SICUTM classification.
- Such distinction may overcome the disparity between the odds ratios generated by the derivation and validation sets of the Cardiac Risk Index (Lee T H. Marcantonio E R. Mangione C M. Thomas E J. Polanczyk C A.
- Classes 3 and 4 are associated with dysfunction that is reflected in the Cardiac Risk Factors (discussed in text).
- Bold indicates the six variables of the Cardiac Risk Index (discussed in text). Italics indicate that, although it will contribute to indications for cardiac evaluation, this feature likely would not prompt initiation of beta-blocker therapy for cardioprotection. (Note - indications must be weighed against contraindications - not listed) . . .
- Cardiac Risk Index excluded variables that have been considered vital to other indices for risk assessment and algorithms for diagnosis and treatment. This effect may be mitigated by a common database enabled by SHAPETM such as the one in Table 17a which enables a common language and scoring system for the otherwise disparate indices and algorithms. No longer must health care decisions be based on an index that is isolated from other indices.
- Cardiac Risk Indices variables are listed below along with quotes from relevant sections of FIG. 32 and Tables 10a and 10b that either are the given Risk Index variable or list a feature (with its score) which is suited to the given Risk Index variable.
- the score provides additional information compared to the Cardiac Risk Index—precise features as well as score—while being programmed to maintain the simplicity of use.
- SHAPETM enables the potential to reduce the common language to scored “cardiac risk” equivalents based on CARD ischemia , CNS ischemia ENDO diabetes , VASC pvd , RENAL insuff of SISSTM and CARD of SICUTM. Examples of this include the designation of the following subsystems (as shown in FIG. 32 ) as independent of the parent body system for purposes of co-population of cardiac risk indices and diagnostic and treatment algorithms:
- the integrated common language and scoring of the present invention may be referred to as SHAPETM Cardiac Risk Assessment Points (SCRAPTM).
- SCRAPTM Cardiac Risk Assessment Points
- the points could be included in Risk indicators of the ASPIRINTM display, or as an independent inventive index, or as a component of SMASHTM. Decisions may be made based on the number of factors that are present, the presence of one or more factors exceeding a given cutoff and/or cumulative score.
- the incorporation the text, code and score conversion dictionary ( FIG. 11 ) enables development of a common language with a common score and a common terminology (and a mechanism for documentation terminology equivalency or similarity) that can be modified in accordance with its score for multiple sites of co-population.
- the inventive dictionary converts statements to a common language for co-population while also providing important details about the nature of the disorder and its severity.
- the unique combination of universal terminology and coding and scoring also may be applied to SHAPETM interactions with scoring systems such as ICD-9 codes and CPT codes as discussed below in greater detail.
- Table 17 uses such a common language and SCRAPTM to collectively cite the Cardiac Risk Indices of Lee and colleagues with the ACC/AHA guidelines for cardiac evaluation, as well as to generate a score for initiating cardioprotection with beta-blockers.
- the scores demonstrate how the SISSTM and SICUTM scores can be included in such algorithms.
- the values for the clinical risk factors are identical to those of the Cardiac system in the SHAPETM database.
- the scores for surgery have been modified to expand the intermediate risk surgery from a single score of 3 to options for 2, 3, or 4 (as described earlier in this document).
- Exercise tolerance is unique among cardiac signs and symptoms in that it is a form of a daily life test: whereas poor exercise tolerance (high score on SHAPETM 1-5 or 0-5 scale) may confirm other signs and symptoms of cardiac disease, good exercise tolerance (low score) lessens the likelihood that the patient has significant cardiac disease.
- the adaptation of SHAPETM to assign negative points to diagnostic and therapeutic guidelines not only enables more effective scoring of indications (as for determining the need for a cardiac evaluation) but also enables quantification of contraindications.
- Negative numbers can be assigned to specific items in specific algorithms; e.g., for a history of severe allergy to beta-blockers in the beta-blocker algorithm, for the presence of severe pulmonary hypertension in a scoring system designed to determine whether one should monitor with an invasive pulmonary artery catheter (which may cause pulmonary artery rupture in a patient with severe pulmonary hypertension).
- the degree of negativity can be graded, with a predetermined value indicating an absolute contraindication.
- Advantages of the inventive mechanism of organizing, coding and scoring in this context include those related to the introduction of a universal language with scoring, as described above.
- the embodiment shown in Table 17 provides more information than the ACC/AHA Guidelines which does not account for uncertain exercise tolerance and does not take into account the number of risk factors or gradation of an individual factor's severity. Additionally, increased precision is provided by the 1-5 classification of surgery (especially with the system-specific SICUTM score).
- the use of a common language and standardized scoring systems enables smooth transition among applications such as the SHAPETM-modified ACC/AHA Guidelines and indications for beta-blocker therapy.
- information from the cardiac evaluation may be used to determine beta-blocker use (while obviously not influencing the decision to perform an evaluation because it was generated by the evaluation).
- the information e.g., from an echocardiogram or stress test
- the inventive modifications may be entered as a new potential scored “risk factor” or as justification for modifying the score of an existing factor.
- inventive modifications e.g., common language and scoring
- exports from SHAPETM may be used to co-populate other indices such as those that calculate Respiratory risk or likelihood of postoperative nausea and vomiting.
- the SISSTM and SICUTM scores can initiate jumps to suggested (default) testing batteries which may be modified as deemed appropriate.
- These can be coded (color, size, 1-5 class) in such a way so as to designate whether the test(s) is strongly indicated or simply should be considered. For example, for patients with thyroid disease a complete set of thyroid function tests likely would be indicated for a SISSTM 4 degree of dysfunction. However, they should be considered, but not necessarily obtained, for a class 2 score.
- FIGS. 21 A and 21 Bb illustrate how driving (generating or suggesting) of testing may be accomplished.
- they a) show how epidemiologic factors and the surgical invasiveness score drive test and b) show how specific medical conditions identified in the score assigned in accordance with the present invention may contribute to the tests that are ordered.
- the integration of laboratory results is discussed with a preferred embodiment described below.
- options for optimization may be selected. This may include new therapies or generation of a consult request ( FIG. 18 ). This can be done with a letter code, e.g., “con”, and then you could have cardiac or pulmonary. This would not only notify other healthcare providers that there is additional workup being done, but also that there is a chance for further optimization.
- the need for, and/or pending requests for, additional information can co-populate the “I” of ASPIRINTM.
- the present invention can provide medical practitioners with other important information that often is lost in the communication process; for example, that the patient refuses blood or has autodonated his/her blood for use during surgery.
- This option can be accessible at any time but may be prompted by the surgical score assigned to the patient (for example, if the SOCUTM score is 4 or 5 or, more specifically, if the SICUTM score for impact on the Hematologic System is 4 or 5.). Provisions for its appearance are provided by “R” and/or “N” of the ASPIRINTM display.
- ASPIRINTM display where a graphical user interface is displayed
- data may be available but not visible to avoid cluttering and/or to maintain confidentiality.
- information can be stored in a computerized database. It also can be coded. Additionally, the presence of additional information can appear as an icon which generates a drop-down menu or jump by clicking on it or with a simple mouse over.
- the EKG is the one pictoral component of the patient's record for which text and/or score often is insufficient. Textual descriptors do not relate nuances of the actual tracing or enable optimal comparisons of EKGs obtained at different dates and times. If the score for the EKG is 1 in the current 1-5 (or 0 in the proposed 0-5) system, then the report of the EKG generally is sufficient.
- a score of ⁇ 2 may trigger inclusion of an EKG, if it is available electronically, in the note (If this option is available, it may be activated automatically by selecting a relevant feature in EKG subsystem, by choosing an include EKG option in the program; or access to the EKG may be obtained in the Information section of the ASPIRINTM display (as shown in FIGS. 5 and 15 ).
- a typical embodiment of the program and graphical user interface screens begins with industry-standard recording or importing of basic information about the patient (e.g., name, medical record #, date of exam, date of planned surgery, name of surgeon).
- basic information about the patient e.g., name, medical record #, date of exam, date of planned surgery, name of surgeon.
- the name of the surgical procedure is recorded at the time of surgical scheduling. Otherwise, it can be hand-entered at this time, preferably by selecting from a pick list.
- the information that already is hard-coded will include not only the standard codes for the surgical procedure but also the inventive surgical risk/invasiveness score (1-5 or 0-5) and the inventive SICUTM score, wherein the anticipated impact on specific systems is delineated for scores where the impact is >2 (or another predetermined value).
- the healthcare provider performing the history and physical typically will include a description of the present illness at the beginning of his/her note. This can be designed to co-populate the affected body system and relevant Risk indicators.
- the screens will also provide the option to jump immediately to that system and work off its screens (and hard-coded choices).
- the screens for Allergies, Medications, Social History/Habits, Prior Surgeries and Anesthetics will be similar to that of other body systems with the added provisions for co-population (e.g., of different sections of the SHAPETM program and ASPIRINTM display). Allergies ideally will be selected from a pick list.
- the selected allergy will be hard-coded to co-populate other screens such as the Risk indicator screen of the ASPIRINTM display or to specific body systems in the review of body systems.
- a user-generated jump will be available (e.g., right clicking, clicking a button which prompts such co-population, or selecting from a drop-down menu). Medicines will be handled similarly to allergy.
- Social History/Habits e.g., tobacco, alcohol, drugs
- relevant patient body systems e.g., smoking may automatically be recorded as 1.5 in the RESPIRATORY system
- Prior surgeries will ideally be obtained from a pick list with options for type-in as in other parts of this program.
- Prior anesthetic experiences likewise will be obtainable from a pick list with options to type in as per above and options for co-population.
- the review of body systems may begin with a screen which lists all possible body systems (including the aforementioned option to select a Multisystem disorder).
- One option is to select all the body systems that are positive so that the computer can subsequently enable all of those in sequence.
- it may be preferable to proceed through each body system sequentially as the history is being obtained.
- the CENTRAL NERVOUS SYSTEM CNS
- the computer will proceed to the next body system, PSYCH.
- PSYCH body system
- more specific choices will be enabled.
- this may entail a variety of options for data entry, including:
- the final note can be configured either to simply ignore all negatives or to display the negative subsystems as a group which is designated as being negative (e.g., “Negative for . . . ”).
- Negative for . . .
- Those skilled in the art will certainly appreciate there are multiple alternative configurations that would be suitable for the aforementioned selection process; e.g., a drop-down menu with “No” as the default.
- the inventive mechanism of coding and scoring systems according to a 1-5 scale may be accomplished in a variety of ways, each of which has its advantages and disadvantages:
- the next section of this disclosure will focus on a preferred mechanism for arranging hard-coded choices with branched-chain logic and for adding information from free typing or importing from other data sources.
- the section also addresses the use of the text, code and score conversion dictionary illustrated in FIG. 10 and the associated interactive index.
- the last aspects of the invention to be described will be: the integration SHAPETM with other coding systems; and the integration of the information generated by the history and physical exam, imports from other sources and laboratory testing into a score-based patient information card (or comparable electronic storage) that records positive information based on the SHAPETM score in a universal language with an established code.
- FIG. 9 shows a representative section of the branched-chain logic—and related coding and scoring—in accordance with a preferred embodiment of the present invention.
- the progressive SHAPETM branched logic first entails division into body systems, consistent with a typical H&P assessment and then progressive, coded branching to more specific (distal) items: System ⁇ Subsystems ⁇ Feature Categories ⁇ Features ⁇ possible Subfeatures and optional Descriptors. Each branch is associated with a specific coding scheme (as detailed in Table 6). These are added sequentially as one proceeds to more distal branches.
- SHAPETM This progression from body system to subsystem to subfeatures and descriptors is consistent with the general to specific questioning of patients.
- the unique advantages of SHAPETM are generated largely by its mechanisms of scoring based on bidirectional branch-chain logic:
- Text, code and score potentially can be entered collectively in a single field or in separate fields.
- scores should be stored in independent fields for score-based assessments, analyses and integrative indices.
- the branching and coding may be flexible. If deemed necessary, additional levels, such as subsubfeatures may be added for a complex system such as Cardiac (although this has not found to be necessary).
- the jump after a hard-coded choice is predetermined.
- This predetermined jump may take one of the following forms: remaining on the current screen so as to enable selection of another choice on the screen; jumping to the next more distal branch on the screen (e.g., from feature category to feature); and moving in parallel manner to another screen within a given branch. This would occur in the following settings: move from one descriptor screen to the next descriptor screen under the same feature or sub-feature; jump from one system to the next if one clicks negative for the system; or jump from one sub-system to the next if one clicks negative for the sub-system. These may be optional, or one may just simply skip negative systems, sub-systems, or feature categories.
- proximal to distal jumping within a given branch may be interrupted by a diversion designated by superscripted letters, symbols or arrows proximal to a screen header or one or more of its hard-coded choices.
- potential predetermined pathways include:
- a subscripted numerical prefix may be used to document co-population of diagnostic and treatment algorithms that are based on information such as that designated by the given item (e.g., diabetes is a risk factor in Cardiac Risk Indices and a potential indication for perioperative beta-blocker administration).
- SHAPETM has multiple type-in options which are designed to maximize specificity of coding and scoring while minimizing complexity for the user.
- Similar Type-in may be accessed by one of several potential options, including a drop-down menu or right-click menu associated with this hard-coded choice.
- a preferred option for coding is for the Similar Type-in to have the same basic code as the hard-coded choice followed by a letter suffix such as the letter “a” (i.e., the basic code before the letter suffix would document the commonality with a hard-coded choice; the letter would designate that it is a type-in).
- Options for storing and communicating the hard-coded choice and type-in include:
- Imported Information The program is designed to facilitate entry, coding and scoring of information imported from other electronic sources such as a computer, fax, or scanner (e.g., patient questionnaire, discharge summary, physician's note, other database).
- the inventive keys to this are entry at the appropriate branch level and establishment of compatibility with text, code and score conversion dictionary ( FIG. 10 ).
- Imported information falls into several categories which may be handled in a variety of compatible ways, including:
- Matching between the import source and SHAPETM may be based on a number of formats, including:
- the handling of imports in this manner provides a uniform way for entering them, coding them, and scoring them in the appropriate sections of the program. It also facilitates tracking them so the program may be updated to become more compatible with other means of data entry (e.g., electronic transfer, faxing, scanning). The number of steps required to ensure such entry will depend on the system compatibility.
- the names and coding of the information in the source of import will be matched to SHAPETM.
- the inventive system includes a conversion dictionary that defines the text, coding (and scoring) interface between SHAPETM and each source of information. This enables matching to a hard-coded choice in the SHAPETM program.
- letters in a suffix may identify the entry as an import, identify its source, and define the degree of similarity to existing hard-coded entries.
- the SHAPETM program contained a hard-coded option “recent CHF with pulmonary symptoms” that was assigned the code 0.0001 $3 and the source of the imported information had a statement “recent pulmonary edema”, then “recent pulmonary edema” would be entered into the program at the level of the aforementioned hard-coded option with a code akin to 0.0001A$3aa.
- the specific letter code suffix would be specific for the given source of input.
- the conversion dictionary could be expandable; if you have a new type-in or import and click yes, then it could be included in the conversion dictionary.
- FIGS. 26-31 include graphical user interface screens of a preferred embodiment that deals with the Central Nervous (CNS) system, the Psychiatric and Pain system, the Diabetes subsystem of the Endocrine system (ENDO diabetes ) and Laboratory Results. These were selected because they cover a wide range of configurations and demonstrate a wide range of program components that relate to branched-chain logic and coding and related scoring. As those skilled in the art will appreciate, this form of branched-chain logic is but one of many ways of coding and scoring that is within the scope and spirit of this invention. As clinical experience is gained with the program(s), screen headings, hard-coded choices, and jumping pathways may be changed while remaining consistent with the inventive coding and scoring disclosed herein.
- CNS Central Nervous
- Psychiatric and Pain system the Diabetes subsystem of the Endocrine system
- Laboratory Results Laboratory Results
- the next screen would be a list of the different subsystems of the CNS system.
- the user either could highlight all positive subsystems or proceed through the positive subsystems sequentially. Either way, selection would enable (activate) screens more distal in the body system. If a subsystem is negative, it simply may be skipped.
- Seizures subsystem If one selected the Seizures subsystem, then this would initiate a jump to a screen of feature categories for the Seizure subsystem ( FIG. 26.1 ).
- the pathway and its standardized punctuation (System: Subsystem: Feature Category/Features//Subfeatures—Descriptors) have been included in many of the headings for purposes of clarity in this demonstration. These details could be available for training sessions but would not be needed for day-to-day use by an experienced user.
- the user would select the feature category that is most appropriate or otherwise type in an alternative. This would cause a jump to the feature screen for the given feature category.
- the first such screen is shown here as a series of scored features under the heading Control of Generalized Tonic-Clonic Seizures ( FIG. 26.2 ).
- the screen would jump to the feature categories that are shown. Selection of a given feature category jumps to a screen with the features for that category. As opposed to the Seizures subsystem, where scoring was at the feature level, in the present subsystem unscored features have been included for each feature category. Selection of an unscored feature enables a scored subfeature screen and causes a jump to that screen. Consistent with the aims of the present embodiment, jumps to descriptors are configured so that they occur after the scoring so as to ensure consistency and inclusion of desired details in the final note and database without concern about affecting scoring by the degree of description that is provided. (although helpful, this is not a requirement for other applications of SHAPETM).
- the jumps to genetic screens occur after the selection of a hard-coded choice.
- the generic screen may be customized so the most relevant choices for a given jump to that screen may be highlighted (or similarly designated).
- the first feature category of “CNS: Cerebral Ischemia” ( FIG. 26.10 ) is “Asymptomatic Carotid Disease”. If this is selected, a series of unscored features is provided ( FIG. 26.11 ). Selection of a hard-coded choice on this screen causes a jump to a subfeatures screen ( FIGS. 26.12 , 26 . 13 or 26 . 14 ) which illustrates two unique aspects of the program noted above: scored subfeatures (after unscored features or features with a tentative score, as opposed to more established default score); and letters in the prefix designating the jumping pathway after choice selection on the given screen. Each scored subfeature is associated with a default score, which may be changed by the user.
- This screen also provides an option for Type-in with a prompt for the user to select a score. This obviates a major shortcoming of other data acquisition programs—where Type-ins typically are not coded or scored. As noted above, free-typing would be associated with a hard-coded choice and the type-in option would be accessed via that choice so as to optimize coding and scoring.
- TIA trans ischemic attack
- stroke initiates similar jumps to an unscored features screen ( FIG. 26.15 ) which delineates timing and then to a scored subfeatures screen (TIA on FIGS. 26 . 16 - 26 . 18 ; stroke on FIGS. 26 . 19 - 26 . 22 ).
- the heading for each subfeature screen in this part of the program is preceded by a series of English letters which take one sequentially through the screens for generic CNS descriptors a-g (FIGS. 27 . 1 - 27 . 7 ).
- the sequence of Generic CNS Descriptors for TIA or Stroke bypasses the screens specific to seizures; instead, it includes screens that detail neurological signs and symptoms.
- Cerebral Ischemia Feature Categories screen for typing information about other forms of cerebral ischemia if they should occur by selecting “Unspecified Cerebral Ischemia” or “Other” as described below.
- the last feature category for the Nonischemic Cerebrovascular Disorders subsystem is the Headaches feature category. If one selects this feature category, then one jumps to an unscored feature screen for Type of Headache. Depending on which feature is selected from this screen, one jumps to the scored subfeatures of mild, moderate, severe, or life-threatening (FIGS. 26 . 33 - 26 . 36 ).
- the feature category screen which lists different nonmalignant masses ( FIG. 26.37 ).
- the subsequent unscored feature screen lists potential tumor locations ( FIG. 26.38 ).
- the subfeature screen contains scored hard-coded choices ( FIG. 26.39 ). This screen is followed by two descriptor screens (FIGS. 26 . 40 - 26 . 41 ; the “Yes” selection on the second screen is preceded by English letters delineating jumps to generic CNS screens (FIGS. 27 . 2 - 27 . 7 ).
- the next screen illustrates what would happen if one selected radiation, either alone or in conjunction with chemotherapy. It prompts the user to include whatever information might be relevant and available (optional) and then jumps to the relevant side effect screen where one is prompted to either say that there were no side effects or to list them and their impact.
- FIG. 26.48 The next screen dealing specifically with the Central Nervous System concerns Intracranial Trauma and Injury ( FIG. 26.48 ). After selecting a feature category which will be listed in the note, the user jumps to a common feature screen for all of the listed feature categories ( FIG. 26.49 ). Scoring occurs at the subfeature level ( FIG. 26.50 ).
- the next series of screens handles CNS infection in a similar manner (FIGS. 26 . 51 - 26 . 53 ).
- Some (a partial representation) of the potential infections that may be included on this list are included as feature categories. For each of the specific infections, the user jumps to a common feature screen that has the signs and symptoms along with their scores.
- the next series of screens deals with ICP (intracranial pressure) (FIG. 26 . 54 - 26 . 56 ).
- ICP intracranial pressure
- the feature category screen lists potential causes (see FIG. 26.54 ).
- FIG. 26.55 there is a common screen which lists and scores the signs and symptoms (see FIG. 26.55 ).
- provisions for an item such as ICP are unique in that it is also listed as a sign/symptom in the generic CNS screen for global CNS signs and symptoms ( FIG. 27.2 ). Because it is listed as a separate sub-system, its inclusion in the generic CNS screen for global CNS signs and symptoms is preceded by a double-sided arrow. This arrow would prompt a jump to the ICP signs and symptoms feature screen so as to ensure that the details of increased intracranial pressure are addressed at this time or at another portion of the program (discussed above).
- the final two screens of FIG. 26 deal with the sub-system of Parkinsonism and other CNS-based movement disorders (FIG. 26 . 59 - 26 . 60 ).
- the feature category screen lists two of the many potential disorders that can be listed on this screen.
- the next screen shows the features of the specific disorder; their severity is rated on this screen.
- the letters preceding the header indicate that there are jumps to other CNS screens to enable selection of unscored descriptors.
- PSYCHIATRIC DISORDERS and PAIN (FIGS. 29 . 1 - 29 . 7 ).
- PAIN PAIN
- FIG. 30 shows typical screens for diabetes mellitus. They are included not only to show the consistency of the branch logic and scoring for another system, but also because diabetes has important implications for other systems and for co-population of risk assessment indices and diagnostic and treatment algorithms; and its features are closely tied to its use of medications. Therefore, I have selected to use it as another example of the inventive system.
- FIG. 30.1 The header on FIG. 30.1 indicates Endocrine System:Diabetes Mellitus subsystem/Feature Categories.
- the next two screens are at the scored feature level—depending on the choice that is selected, the computer will jump to either the screen with the scored features concerning control of Type 1 ( FIG. 30.1 ) or Type 2 diabetes ( FIG. 30.2 ).
- descriptor screens which include:
- selections that may be available on a given screen may actually be an integration of 2 or more features or a feature and a subfeature. For example, it may state “severe hypertensive nephropathy”. This would tell you that there is a severe nephropathy (feature) and there is a hypertensive nephropathy (also a feature). By way of another example, it may state “Pronounced hypoxia requiring continuous oxygen”. This is actually a feature and a subfeature combined, wherein pronounced hypoxia could either be a 3 or 4, but the requirement for continuous nasal oxygen would be a 4. If feature category would be 4, and a given item itself together is 4 to 4.
- the universal application of the present invention thus has been demonstrated with respect to attaining, storing and co-populating (with exporting) the information attained during the history and physical exam.
- the present disclosure will next illustrate how information from two forms of testing—routine laboratory testing (with accepted ranges of normality) and EKGs (wherein clear cut criteria may not exist) may be included.
- Laboratory tests could be recorded as per routine in the institution laboratory database but also co-populate sections of SHAPETM where they can be recorded, coded and scored for storage in a Laboratory (LAB) “system” (or as a subsystem in FLUID & LYTES) as well as with specific body systems (e.g., liver function tests with liver), and/or Risk Indicators, Interim Information and Issues and where they can be used for analysis, display and distribution to interfaced notes, algorithms etc.
- LAB Laboratory
- specific body systems e.g., liver function tests with liver
- Risk Indicators Interim Information and Issues and where they can be used for analysis, display and distribution to interfaced notes, algorithms etc.
- the 1-5 (or 0-5) system is used in a series of screens as illustrated for the lab values for potassium (FIGS. 31 . 1 - 31 . 5 ).
- Inventive formulas convert lab values to scores.
- One such method is shown in FIG. 17 .
- Abnormal values that generate the specified cutoff can trigger score-driven jumps to screens which list medications that commonly cause or are affected by the given abnormality (e.g., low potassium can lead to digitalis toxicity, diuretics can lead to low sodium).
- the abnormal values can be linked to relevant medical conditions and to surgery which may exacerbate the disorder (e.g., transurethral resection of the prostate with bladder irrigation would be identified by the SICUTM score as affecting electrolytes (exacerbating hyponatremia).
- Links will influence level of concern and decisions with respect to treatment of abnormal chemistries. For example, if patient is taking digitalis, this would not only be listed in medication screen but also co-populate CARDIAC system with the option for a separate screen that records Factors Affected by Electrolytes. This would be co-populated with relevant entries from Medications, Fluid and Electrolytes, Kidney, GI as well as sections from the SICUTM score for the upcoming surgery. Hence, the present invention has scoring options for a number of the hard-coded choices.
- Lab Results is a subsystem of FLUID & LYTES.
- the problem with this is that lab results often do not become available until after the History and Physical are obtained.
- system-specific tests preferably should be included in the associated body system—e.g., cardiac stress test in CARDIAC or pulmonary function tests in RESPIRATORY.
- the textual description associated with a score may not be sufficient to effectively relate the abnormality.
- criteria for scoring an EKG have been provided in FIG. 32
- the coding and scoring of the present invention can prompt access to the actual tracing ( FIG. 10 by special notation in the ASPIRINTM display (and relevant sites of co-population) if an electronic version is available (as shown in FIG. 3 ). Otherwise, it may prompt the inclusion of a printed copy with the preoperative note.
- the concise database of text, code and score can be applied to provide patients and their caregivers with compact information about an individual's health status.
- Data can be stored in common language or code, preferably according the logical branched-chain code described below and with respect to FIGS. 26-31 . Selection of information for such storage will depend on the scores of the coded features. For example, it may be limited to conditions which merit a predetermined score (e.g. ⁇ 3) in any of the many components such as SISSTM, SMASHTM or the ASPIRINTM display. If listing is only in code, then the code will relate the system, subsystem, feature category and feature as per FIG.
- a predetermined score e.g. ⁇ 3
- HIPAA-compliant i.e., privacy protected access to all components or selected components with coding.
- HIPAA-compliant i.e., privacy protected access to all components or selected components with coding.
- ⁇ 2 scores beyond an established cutoff (e.g., ⁇ 2) may drive optional storage of additional information beyond that of coded text (typically of test results), including:
- one score is provided as the default score for the given version; e.g., “systemic/current” for the version displayed in FIG. 32 and FIGS. 26-31 , and throughout this document for preoperative assessment.
- Such uniform scoring can be tailored to the given form.
- This concurrent scoring may take the form of a uniform sequence such as systemic current/local current—systemic longterm/local longterm.
- the default score can be changed for each entry.
- a preferred option is a drop-down menu. To accommodate changes because of systemic/local or current/longterm categories, this drop-down menu similarly can enable changing options (with appropriate sequences and/or coding).
- the systemic and local effects, as well as the acute and chronic effects of a given condition may be recorded with separate programs with options for automated co-population of items with equivalent scores in multiple programs.
- two or more scores can be provided in a single database.
- Options include:
- the default score for each included component will be provided (e.g., current systemic for the preanesthetic assessment, with a drop-down or right-click menu for selecting additional scores.
- inventive features described earlier for interfacing with diagnostic and treatment algorithms e.g., the use of a common language, as facilitated by a conversion dictionary, to document the equivalency (or similarity) of different terms and the use of a score to relate severity—are also relevant to interfacing with other coding systems.
- SHAPETM system as a means of exporting inventive codes and scores or portions thereof as well as a means for incorporating codes from other systems into the systemic coding and inventive scoring introduced herein.
- the present invention enables scored coding of conditions, lab results, responses to challenges and therapy, and outcome according to categories such as bodily system and severity of disorder/dysfunction. Moreover, it does so at the time of information entry (into clinical note, primary database, and sites of co-populaton)—not by retrospective case-by-case chart review or reliance on recollection in association with coding texts.
- a preferred embodiment for uniform coding and scoring of different sources of information entails reliance on the inventive system of coding and scoring, with incorporation of the ICD code into items where an ICD-9 code currently is deemed indicated.
- An example is the general history and physical described above. Options are provided in Table 19.
- the preferred embodiment retains sequential numbering for the level of branching (e.g., feature, subfeature, or descriptor) for which the code from the alternative source (e.g., the ICD-9 code) applies.
- level of branching e.g., feature, subfeature, or descriptor
- code from the alternative source e.g., the ICD-9 code
- ICD-9 Options for Interfacing the Present Invention with Other Coding, e.g., ICD-9 1. Include terms associated with specific ICD-9 codes as hard-coded options. Selection could automatically include the ICD-9 code. 2. Include hard-coded choices or screens that are consistent with categories or subcategories of the ICD- 9 system. Selection could automatically jump to a screen wherein the relevant codes and text are listed and/or interface with the appropriate section of the ICD-9 program. 3. Provide options to jump from a given item to a screen(s) with potentially applicable ICD-9 codes and associated terms. 4. Adapt Conversion Dictionary (described in text) to list text and coding synonyms for SHAPE TM vs ICD-9 and enable jumps between them. 5. Click of ICD-9 code, prompting reverse jump to SHAPE TM (Less advantageous because this eliminates many of the advantages of the inventive system, including time of entry coding and scoring, storage in accordance with inventive branched-chain logic).
- FIG. 9 illustrates in tabular form how the present invention may be adapted to include the ICD-9 code (or an alternative code) within the inventive coding system. “a” shows this without an inventive score; “b” shows this with an embodiment for the inventive score ($#) at each level of branching.
- SHAPETM uniform means of coding and scoring described herein is universally adopted (if and when)—it may be more practical to include such information from SHAPETM in the other (e.g., ICD-9 or CPT) code. While inclusion of the entire SHAPETM code (as described above) would provide the most complete information and coding, a reasonable compromise would be to simply include a portion of the code and the system or feature score. Adaptation for procedures may be as simple as modifying the CPT code with the SOCUTM score of the inventive system. This enables the code to provide an indication of risk/invasiveness that otherwise might not be evident. Likewise, the codes for anesthesia relative value units can be annotated similarly.
- the system code may be generated from a common list of systems or via computer by creep seek typing which generates the code for the system in addition to its name.
- Subsystem code may be generated as per above, with the potential to facilitate this with a dropdown menu when a system is selected electronically. Scoring can be generated by the means described for scoring above, with the potential to generate the score electronically if the selection is generated electronically as may be enabled by arrays such as those in Tables 10 and 10b, as well as FIGS. 26-32 .
- the first of these two options is preferable because then the score is assigned at time of entry of the clinical assessment, without the need to review the record to identify the information needed for such coding and scoring.
- the advantages of incorporating established codes within the inventive code may be appreciated in the following example: a patient with advanced diabetes and associated atherosclerotic cardiovascular disease sees a physician because of a nonhealing foot infection with evidence of systemic infection. Since this involves multiple systems, it is cumbersome, at best, to capture the multiple presenting problems and relevant comorbidities with current coding. Incorporating the inventive codes and scores likewise could be cumbersome.
- HPI history of present illness
- a thyroid abnormality requiring surgery may cause: difficulty swallowing, shortness of breath when lying flat, hoarseness secondary to recurrent laryngeal nerve involvement, hypertension, an abnormal cardiac rhythm (e.g., atrial fibrillation), weight loss, and anxiety.
- inventive code/score and established codes may be depend on the configuration of the actual note—are the consequences of the abnormal thyroid listed under HPI, under Endocrine/Thyroid, or under the other affected systems.
- a preferred embodiment entails partial co-population of the relevant sections, with details provided upon jumps to the affected systems/subsystems/feature categories.
- inventive system offers the advantage of coding at the time of information entry as opposed to having to match a code to a diagnosis by retrospective review.
- the integrative function of the inventive program and the associated inventive indices provide for integrated assessments of disorders and challenges and interventions that are not attainable with other programs (Table 2).
- Table 2 The integrative function of the inventive program and the associated inventive indices provide for integrated assessments of disorders and challenges and interventions that are not attainable with other programs (Table 2).
- the widely used CPT (Current Procedural Terminology) code provides a 5-digit code for procedures. These are grouped as “Evaluation and Management, Anesthesiology, Surgery, Radiology, Pathology and Laboratory, Medicine. As is the case for ICD codes, the CPT coding system lacks the score-based coding that typifies the inventive system. As noted in Table 10b, surgeries impact on multiple systems and thus may be not be amenable to the same branched-chain logic as medical conditions. Adaptation for procedures may be as simple as modifying the CPT code with the SOCUTM score of the inventive system. This enables the code to provide an indication of risk/invasiveness that otherwise might not be evident. Likewise, the codes for anesthesia relative value units can be annotated similarly.
- the present invention provides the basis for detailed scored coding based on branched-chain logic with the potential for: 1) incorporation of an existing code such as ICD-9 and CPT; 2) incorporation of the inventive score in those existing codes.
- inventive scores e.g., SISSTM, SOCUTM and/or SICUTM
- inventive system including: amending coding in accordance with the inventive coding and scoring for branched-chain logic; adapting inventive means for categorizing and scoring type-ins and imports; providing for score-driven displays, scripts, exports, and data transmission and storage.
- the overall database can be constructed in a variety of ways, examples of which are shown in FIGS. 13 , 14 and 16 .
- the coding of this embodiment is in accordance with the branched-chain logic shown in FIGS. 26-31 .
- the unpopulated database may include all potential entries (positive as well as negative, likely as well as unlikely) and allot space for imports and type-ins (as shown in this arrangement) or it may be configured so that only the selected (positive) entries are entered.
- the “$” columns enable each scored item to be entered into the appropriate column; the proposed 0-5 scale is shown in this figure. Although potentially requiring more storage space, it may be preferable to assign separate cells to each potential score for a given item.
- the database can be “expanded” to absorb new entries or cells, with rows and/or columns reserved for type-ins or imports related to a given hard-coded item.
- the “reservation” could include all or part of the code and default score (with the potential for customization according to the source of import as with a letter suffix). If the potential source is an established source of import, then the actual text may accompany the code in the reserved cell(s) comparable to the arrangement for hard-coded choices.
- These provisions for add-ins and type-ins can be in columns to the right of the standard hard-coded choices or can be established for entry immediately below the relevant hard-coded choice.
- a separate column can designate the source of the information (e.g., current H&P, surgeon's note . . . ).
- Another column can designate as to sites of co-population and sites of export, in coordination with relationships defined in the conversion dictionary and/or interactive index.
- a given feature, subfeature or descriptor maintains its level-specific code throughout the database; however, if it co-populates different feature categories, subsystems or systems, the proximal portion of its code will differ.
- scoring is based solely on scores assigned to features and subfeatures
- scores assigned to more proximal branch levels are based upon the scores associated with the more distal features and subfeatures.
- level of hard-coded scoring is not limited to features and subfeatures, then it may be important to distinguish between hard-coded and derived scores (e.g., by assigning to different columns, annotating with a letter code, etc).
- the coding and scoring described herein enable simple linking to the details within the inclusive SHAPETM database; e.g., more specifics as to the nature of a patient's class 3 disorder(s) of the Cardiac system as summarized at the end of the sample note ( FIG. 4 ) and enabled by the ASPIRINTM display ( FIGS. 6 and 7 ).
- a single cell e.g., a patient's score for the Cardiac system
- ICD-9 complex array of codes
- a patient's surgical procedure(s) could simply be consolidated according to its overall severity with an inventive code that integrates the risk/invasiveness score and the CPT code, with a link from that single cell to the itemization provided by the SICUTM score when more details are needed about a specific procedure.
- FIGS. 17 through 24 are grids, wherein the inventive score is used to consistently assess components of the SHAPETM database and thereby populate components of the ASPIRINTM display, co-populate other portions of the SHAPETM database, co-populate other databases, and drive related algorithms and scripts.
- FIG. 17 is a grid that shows how the inventive score drives and chronicles ordering and reviewing common laboratory tests.

One or more healthcare providers should be identified (as having reviewed the results) in each “Results” cell for tests cited as “Indicated” (as may be demarcated by shading).
- FIG. 18 is a grid that shows how the inventive score drives and chronicles requesting and reviewing of specialty consultations and specialty testing.
- the code for the source of request is entered to left of the “/” (based on coding described with respect to FIG. 17 ); code(s) for healthcare provider(s) reviewing the information to the right of the “/.”
- FIG. 19 provides the status of Interim Information and Issues (again on a graded (0-5) scale). Items in this figure, as well as in related figures and tables can be coded so as to generate a “stop” or “alert” or be a component of the pre-incision “time-out” if not documented satisfactorily.
- FIG. 20 delineates how the embodiment for driving laboratory testing delineated in FIG. 17 can be applied to liver function tests.
- inventive automated score-driven indications for obtaining the tests are based upon an integration of inventive SISSTM and SICUTM scores (and, when indicated, SASRITM for relevant Risk Indicator).
- hepatic (liver) disease e.g., SISS 4 or 5 for Hepatic system
- SISS 4 or 5 for Hepatic system would likely obtain liver function tests periodically and prior to virtually any challenge.
- SISISSTM score the nature and severity of the condition
- decisions may be overridden and institutions can establish different cutoffs (without compromising the inter-institutional recording and storage of data entry since that may be entered in accordance with established clinical guidelines and is not influenced by what one subsequently does with the entries).
- FIG. 21 is a grid that guides and chronicles ordering of laboratory tests.
- the default “Y” (or demarcation such as shading) indicates testing may be indicated; it may be replaced a 0-5 number as per laboratory indications ( FIG. 17 ).
- FIG. 22 is a grid that shows how the inventive score drives and chronicles decisions about discontinuing a current medication or starting a new medication and/or whether to stop (inactivate) a device such as a cardiac rate management device (e.g., pacemaker or automatic intracardiac defibrillator (AICD).
- a cardiac rate management device e.g., pacemaker or automatic intracardiac defibrillator (AICD).
- the appropriate cell(s) is/are shaded (by co-population) if given medication is listed in history and physical or in another source of information (e.g., questionnaire) or, in the case of possibly initiating a medication, if a designated indication (as mediated via text, code and score conversion index and dictionary) is recorded. If item is activated without a score, then cells may simply be shaded.
- a designated indication as mediated via text, code and score conversion index and dictionary
- Code(s) for source(s) of request to address the issue entered to the left of the “/” (based on coding described with respect to FIG. 17 ); code(s) for healthcare provider(s) generating the order to the right of the “/.” As per FIG. 17 , the same healthcare often would be designated before and after the “/.” A “/” (or an entry to the left of the blank) may not be needed, unless the healthcare provider who identifies the need to make a decision defers the decision to a colleague (e.g., to the cardiologist).
- FIG. 24 shows how representative ASPIRINTM scores can uniformly drive myriad decisions with respect to basic testing, consultations, preop assessment by an anesthesiologist, suitability for fast track discharge from the post anesthesia care unit, and/or likely need for postoperative intensive care unit management. It also illustrates how the inventive system can be applied to nonoperative settings.
- FIG. 24 illustrates how potential scores may automatically drive the testing, consults and decisions. These decisions may be adjusted in accordance with clinician input.

Abstract
A multi-dimensional system for assessing, coding, quantifying, displaying, integrating and communicating information relating to patient health and perioperative risk includes a mechanism for inputting patient information and providing an output relating to the patient health and perioperative risk. The output includes a score for the physical condition of the patient, a score for the degree of expected surgical risk and invasiveness, a score for other vital assessments of perioperative complexity, and alphanumeric codes for other factors that may require special preoperative preparation and planning.
Description
This application claims the benefit of U.S. Provisional Patent Application Ser. No. 60/772,559, entitled “Method and System for Assessing & Communicating Perioperative Risk”, filed Feb. 13, 2006, and U.S. Provisional Patent Application Ser. No. 60/839,112 entitled “Method and System for Assessing, Quantifying & Communicating A Patient's Perioperative Health and Perioperative Risk”, filed Aug. 22, 2006.
1. Field of the Invention
The invention relates to a method and system for integrated assessment, coding and scoring of overall health and, more specifically, at times when communication and decision-making are particularly crucial such as in the assessment of perioperative risk.
2. Description of the Related Art
The complex physiological demands wrought by anesthesia and surgery may have a significant impact on a patient's pre-existing medical conditions, necessitating a vital role for anesthesiologists as perioperative as well as intraoperative physicians. While the medical imperative for this role is substantial, the health system framework required for its optimal execution is comparatively weak. The financially driven migration of inpatient surgeries to day-of-surgery admissions and outpatient procedures has virtually eliminated face-to-face conversations among clinicians at the patient's bedside on the evening prior to surgery. Moreover, the anesthesiologist caring for the patient no longer is assured access to the patient (or detailed information about the patient) prior to the day of surgery. In some centers, this lack of communication has led to establishment of pre-admission centers that integrate assessments by the anesthesiologist, surgeon, long-term care provider, and consultant. However, in many cases, the multifaceted process of preoperative assessment and preparation has become the primary responsibility of either a primary care physician without first-hand knowledge of the operative plan or of an anesthesiologist or surgeon with limited knowledge of the patient's long-term care.
Furthermore, for those institutions where preanesthesia evaluation clinics exist, they are frequently staffed by non-anesthesiologists or an anesthesiologist who will not be in charge of the patient's intraoperative care. In the absence of a well-developed information network, this opens the substantial risk of important clinical data being lost or misinterpreted within a series of information transfers. In addition, the presence of multiple care providers (for example, surgeon, anesthesiologist, internist, consultants) in the face of imprecise role definitions all too frequently results in errors of omission due to unreliable communication. The present invention was prompted to fill the void (that is, loss of the “bedside” encounter) imposed by day of surgery admissions with an even more effective, universally applicable means of assessment and communication.
It has been suggested that perioperative risk be interpreted as being influenced by two major components: the patient's physical status and the planned surgical invasiveness. Lema M J, Using the ASA Physical Status classification may be a risky business, ASA Newsletter 2002; 66(9).
In the early 1940s, the American Society of Anesthesiologists (ASA) had the wisdom to design a simple 1 to 5 score that would enable anesthesiologists to communicate the severity of a patient's illness among themselves and with physicians in other specialties. This resulted in what is currently known as the ASA Physical Status (PS) Classification System. One of the stated purposes of the endeavor was to develop a means by which to develop statistical data about anesthetic outcomes by controlling for differences in a patient's underlying medical conditions. Saklad M., Grading of patients for surgical procedures, Anesthesiology 1941 May:281-284.
Sixty years later—with only minor revisions despite major advances in anesthesia, surgical and medical care—the ASA PS system remains the most widely used patient classification scheme in anesthesiology.
While its simplicity is one of its strengths, it is also one of its limitations. The ASA PS score does not distinguish between disorders of different systems or the nature of different disorders within the same system. Rather, it provides a single number to represent the systemic severity of the patient's overall medical condition. Hence, a given score does not guide preparation for a patient with asthma vs. renal disease vs. cardiac disease vs. metastatic malignancy. Moreover, it does not delineate or cumulate risk based upon multiple disorders. This has prompted the inventor to hypothesize that, with respect to the ASA score, the whole is less than the sum of its parts. In a recent assessment of 220 patients that underwent preoperative assessment under my supervision at a tertiary care medical center and received an ASA physical status score of 3 (significant systemic condition), or 4 (life-threatening systemic condition):
-
- the distribution among bodily systems was not uniform, with 55.7% having what the inventive system described herein would rate as a ≧3 (on a 1-5 scale) cardiac disorder;
- 30.4% of patients had two systems affected by significant dysfunction, 14.1% had three systems, and 2.1% had four systems.
Other methods of classifying patients with respect to physical condition have been developed, but these have tended to focus on discrete subpopulations. Several authorities have developed systems for stratifying perioperative cardiovascular morbidity and mortality. Palda V A. Detsky A S, Perioperative assessment and management of risk from coronary artery disease, [Review, Tutorial] Annals of Internal Medicine, 127(4):313-28, 1997 Aug. 15., Detsky A S, Abrams H B, Forbath N, Scott J G, Hilliard J R, Cardiac assessment for patients undergoing noncardiac surgery. A multifactorial clinical risk index, Arch Intern Med 1986; 146(11):2131-4. These systems typically emphasize cardiovascular evaluation to the exclusion of other disease processes. In the critical care literature, the development of risk stratification indices also has been popular. However, these systems, which include the Charlson Comorbidity index, Mortality Probability Model and APACHE score, focus on disorders with high morbidity and mortality that do not necessarily pose as high a risk as other conditions in the acute perioperative period. For example, the Charlson index provides scores of 1 and 6 for prior myocardial infarction (a finding that significantly increases the risk of an adverse cardiac event in the perioperative) and metastatic malignancy, respectively Scales D C, Laupacis A, Pronovost P J, A systematic review of the Charlson comorbidity index using Canadian administrative databases: a perspective on risk adjustment in critical care research, Journal of Critical Care 2005; 20(1):12-19. (As will be shown later, the indices have little in common with the major components of the present invention.
Scoring systems have also been described for specific disorders. For example, the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure classifies three stages of hypertension: prehypertension (systolic 120-139 mmHg, diastolic 80-89 mmHg), Stage 1 (systolic 140-159 mmHg, diastolic 90-99 mmHg), and Stage 2 (systolic>160 mmHg, diastolic>100 mmHg) in light of the direct relationship between elevated blood pressure and risk of morbidity. Similarly, the New York Heart Association defines four classes of heart failure based on degree of physical limitation—from no limitation (Class I) to incapacitation (Class IV). Examples exist for noncardiac disorders as well. For example, the Child-Pugh score provides a means to grade the severity of liver disease based on clinical symptoms and laboratory data; and five stages of renal dysfunction have been delineated by the National Kidney Foundation based on glomerular filtration rate. Other rating systems integrate signs and symptoms to generate qualitative gradations by which the severity of the condition and the adequacy of therapeutic management are judged. For example, diabetes control is evaluated based on glycosylated hemoglobin, insulin requirements, blood glucose readings before and after meals, tendency for harmful extremes, and end-organ injury. Scoring of asthma severity is based on frequency and severity of symptoms and inhaler use.
Relative to these systems, the assignment of ASA PS is significantly more subjective. For this reason, it is not surprising that numerous studies have demonstrated significant inter-rater variability in scoring, leading some to doubt the ASA PS's clinical utility particularly when used as a communication tool among practitioners. Aronson W L, McAuliffe M S, Miller K, Variability in the American Society of Anesthesiologists Physical Status Classification Scale, AANA J 2003; 71 (4):265-274; Mak P H, Campbell R C, Irwin M G, American Society of Anesthesiologists. The ASA Physical Status Classification: inter-observer consistency American Society of Anesthesiologists. Anaesth Intensive Care 2002; 30(5):633-40; Owens W D, Felts J A, Spitznagel E L, Jr., ASA physical status classifications: a study of consistency of ratings, Anesthesiology 1978; 49(4):239-43; Ranta S, Hynynen M, Tammisto T, A survey of the ASA physical status classification: significant variation in allocation among Finnish anaesthesiologists, Acta Anaesthesiol Scand 1997; 41(5):629-32. Nonetheless, there are several reasons why, despite its shortcomings, the ASA PS system has endured. First, it can be determined based on information obtained from a history and physical examination without the need for additional data. Second, its five-point scoring system is intuitive and easy to remember. In addition, unlike other illness severity scoring tools, the ASA PS was designed to be applied to patients of all ages, medical conditions, and degrees of health.
The ASA PS was intended to reflect the condition of an individual irrespective of the planned surgical procedure. However, without knowing the degree of surgical invasiveness planned, the ability to assess perioperative risk is limited. Hence, the need for a system by which to classify surgical severity was recognized; and several surgical risk scoring systems have been proposed. Brooks M J, Sutton R, Sarin S, Comparison of Surgical Risk Score, POSSUM and p-POSSUM in higher-risk surgical patients, Br J Surg 2005; 92(10):1288-92; Pasternak L R, Preoperative evaluation, testing, and planning, Anesthesiol Clin North America 2004; 22(1):xiii-xiv; Pasternak L R, Preanesthesia evaluation of the surgical patient, Clinical Anesthesia Updates 1995; 6(2):1-12; Eagle K A, Berger P B, Calkins H, et al., ACC/AHA guideline update on perioperative cardiovascular evaluation for noncardiac surgery: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Committee to Update the 1996 Guidelines on Perioperative Cardiovascular Evaluation for Noncardiac Surgery). 2002.}. The American College of Cardiology/American Heart Association (ACC/AHA) has divided surgeries into low-, intermediate- and high-risk in its guidelines for preoperative evaluation of patients with coronary artery disease. Eagle K A, Berger P B, Calkins H, et al., ACC/AHA guideline update on perioperative cardiovascular evaluation for noncardiac surgery: a report of the American College of Cardiology/American Heart Association Task Force on Practice Guidelines (Committee to Update the 1996 Guidelines on Perioperative Cardiovascular Evaluation for Noncardiac Surgery), 2002. Pasternak and colleagues proposed the Johns Hopkins Risk Classification System. Pasternak L R, Preoperative evaluation, testing, and planning, Anesthesiol Clin North America 2004; 22(1):xiii-xiv; Pasternak L R, Preanesthesia evaluation of the surgical patient, Clinical Anesthesia Updates 1995; 6(2):1-12. The John Hopkins Risk Classification System employs a five-level classification based on location and extent of surgery, anticipated blood loss and fluid shift, postoperative anatomic and physiological alterations and the need for postoperative intensive care monitoring. Of note, the 3-tiered ACC/AHA and 5-tiered Pasternak rankings are not interchangeable.
The importance of having a means by which to assess surgical risk as well as preoperative patient evaluation is now well appreciated. In a retrospective study in Great Britain, Fowkes et al. found surgical condition to be the most often cited cause of perioperative death, followed by the severity of the patient's underlying medical condition. (“Anesthesia” was the third most common factor to be implicated). Fowkes F G, Lunn J N, Farrow S C, Robertson I B, Samuel P, Epidemiology in anaesthesia. III: Mortality risk in patients with coexisting physical disease, Br J Anaesth 1982; 54(8):819-825. More recently, the ASA Task Force on Preanesthesia Evaluation made this point clear when advising evaluation by an anesthesiologist prior to the day of surgery not only for ASA 3 or 4 patients but also for relatively healthier ASA 1 or 2 patients undergoing highly invasive, high-risk surgical procedures. American Society of Anesthesiologists Task Force on Preanesthesia Evaluation, Practice advisory for preanesthesia evaluation: a report by the American Society of Anesthesiologists Task Force on Preanesthesia Evaluation, Anesthesiology 2002; 96(2):485-96. Data obtained under my direction at a tertiary care center documented the effects of the ASA PS score and surgical risk/invasiveness on hospital length of stay (FIG. 1 ).
The relative weighting of variables and the specific formula to predict outcomes can be generated by multivariate logistic regression and other forms of analysis as well as empirical observation. For example, based on the derivation data set of the aforementioned study, the weighted influence of the ASA physical status score and the surgical invasiveness score is shown by the following regression equation generated from the data:
Hospital Charges ($)=e [(7.6+0.35(ASA)+0.56(SOCU)−0.55(ASA)(SOCU)]
Hospital Charges ($)=e [(7.6+0.35(ASA)+0.56(SOCU)−0.55(ASA)(SOCU)]
While, to a certain extent, the combination of ASA PS and degree of surgical invasiveness would suggest the degree of anesthetic risk, there are other factors that impact on anesthetic complexity and perioperative morbidity and mortality. If identified prior to the day of surgery, they likely would be amenable to risk management interventions. The literature is replete with recommendations as to how to characterize, plan for and manage what may be termed “non-ASA PS score, non-surgical invasiveness” factors that affect anesthetic complexity and potentially impact of patient morbidity. However, to the best of my knowledge, until the development of the present invention a system for incorporating these factors in a communicable score was lacking—hence, vital information may not be readily transmitted to the operating room schedulers and intraoperative caregivers and to databases for quality assurance, outcome, financial, resource allocation, and investigative analysis.
Complications of airway management are the most common cause of anesthetic-related catastrophes. Lee L A, Domino K B, The Closed Claims Project. Has it influenced anesthetic practice and outcome? Anesthesiol Clin North America 2002; 20(3):485-501; Cheney F W, The American Society of Anesthesiologists Closed Claims Project: what have we learned, how has it affected practice, and how will it affect practice in the future?, Anesthesiology 1999; 91 (2):552-6; Caplan R A, Posner K L, Ward R J, Cheney F W, Adverse respiratory events in anesthesia: a closed claims analysis, Anesthesiology 1990; 72(5):828-33. For this reason, identification of the potentially difficult airway has been an ongoing clinical endeavor. The Mallampati score of oropharyngeal view has provided some uniformity to prediction of endotracheal intubation difficulty, but is woefully incomplete. Mallampati S R, Clinical sign to predict difficult tracheal intubation (hyothesis), Can Anaesth Soc J. 1983; 30(3 Pt 1):316-317; Mallampati S R, Gatt S P, Gugino L D, et al., A clinical sign to predict difficult tracheal intubation: a prospective study, Can Anaesth Soc J. 1985; 32(4):429-434; Needham D M. Bellhouse C P, Dore C, Predicting difficult intubation, Br J Anaesth 1989; 62(4)469; Combes X, Le Roux B, Suen P, et al., Unanticipated difficult airway in anesthetized patients: prospective validation of a management algorithm, Anesthesiology 2004; 100(5):1146-50; el-Ganzouri A R, McCarthy R J, Tuman K J, Tanck E N, Ivankovich A D, Preoperative airway assessment: predictive value of a multivariate risk index, Anesth Analg, 1996; 82(6):1197-1204; Ovassapian A, Glassenberg R, Randel G I, Klock A, Mesnick P S, Klafta J M, The unexpected difficult airway and lingual tonsil hyperplasia: a case series and a review of the literature, Anesthesiology 2002; 97(1):124-32; Yamamoto K, Tsubokawa T, Shibata K, Ohmura S, Nitta S, Kobayashi T, Predicting difficult intubation with indirect laryngoscopy, Anesthesiology 1997; 86(2):316-321. Furthermore, it does not address other aspects of airway management, most notably potential difficulties associated with ventilation (e.g., via a face mask) and risk of aspiration or precipitous desaturation.
In addition to the airway, issues potentially critical to anesthesia management that should be communicated include conditions such as prior halothane hepatitis or porphyria (a disorder of blood cell enzymes); communication problems; emergency surgery; presence of an AICD (automatic intra-cardiac defibrillator); latex allergy; risk of malignant hyperthermia; morbid obesity; pregnancy; and potential for signs and symptoms of acute withdrawal. Of these, the only one that is communicated as part of the ASA score is emergency surgery, which is designated with an “E” after the numeric score to indicate that there may not be time to optimize the patient's condition preoperatively (a factor that results in a higher level of reimbursement).
It should be noted that, with current practices at a major medical center (without the information provided by the present invention), anesthesiologists reported that they either overestimated or underestimated subsequent case complexity based upon the information available on the operating room schedule in approximately 25% of cases (data obtained by my research team presented at the American Society of Anesthesiologists annual meeting in October 2006 after initial filing of this disclosure).
The need for the present invention and its potential in the perioperative period as well as for consistency, integration, communication, quality and efficiency of overall medical care is evident by the multiple urgings for change summarized in Table 1.

“different risk-adjustment methodologies afford divergent estimates of mortality risk.” |
The problem (which is not limited to the perioperative period) is that the disparate nature of terminology, classification, coding and scoring has been allowed to metastasize, with disparate systems for clinical evaluation, special testing, decision making, communication, resource allocation, quality assurance and research applications. To date, problems in these areas have been addressed with band aids or by trying to adapt programs designed to solve a different problem.
This invention cures these problems treats the underlying “illness” by introducing a new mechanism for data entry, coding and scoring and a mechanism to enable universality among clinical, communicative, administrative and investigative components. The seamless integration of data is enabled with little or no added burden to the clinician in that main impact of the invention is on the information after it has been accrued by the patient's healthcare providers.
Limitations of Other Coding Systems:
The most widely used means for coding medical conditions is the 9th revision of the International Classification of Diseases (ICD, with latest version at time of this submission being ICD-9) system, as detailed in ICD-9-CM for Physicians. (Ingenix, Inc. 2006) (for codes valid Oct. 1, 2005 through Sep. 30, 2006). As noted in that text, “coding today is used to describe the medical necessity of a procedure which then facilitates payment of health services, to evaluate utilization patterns and to study the appropriateness of health care costs.” As noted on p1 of that text, ICD-9 coding is a complex process: “A joint effort between the healthcare provider and the coder is essential to achieve complete and accurate documentation, code assignment and reporting of diagnoses and procedures . . . The entire record should be reviewed to determine the specific reason for the encounter and the conditions treated.”
The following “10 STEPS TO CORRECT CODING” cited by Ingenix's 2006 version of ICD-9-CM for Physicians illustrates the complexity of the ICD system, which is far greater than that of the inventive system. That text states:
-
- Step 1: Identify the reason for the visit (e.g., sign, symptoms, diagnosis, condition to be coded).
- Step 2: Always consult the Alphabetic Index,
Volume 2, before turning to the Tabular List. - The most critical rule is to begin a code search in the index. Never turn first to the Tabular List (Volume 1), as this will lead to coding errors and less specificity in code assignments. To prevent coding errors, use both the Alphabetic Index and the Tabular List when locating and assigned a score.
- Step 3: Locate the main entry term.
- Step 4: Read and interpret any notes listed with the main term.
- Step 5: Review entries for modifiers
- Step 6: Interpret abbreviations, cross-references, symbols and brackets. Cross references used are ‘see,’ ‘see category’ or ‘see also.’ The abbreviation NEC may follow main terms or subterms. NEC (not elsewhere classified) indicates that there is no specific code for the condition even the medical documentation may be very specific. The ✓ box indicates the code requires an additional digit. If the appropriate digits are not found in the index, in a box beneath the main term, you MUST refer to the Tabular list. Italic brackets [ ] are used to enclose a second code number that must be used with the code immediately preceding it and in that sequence.
- Step 7: Choose a tentative code and locate it in the Tabular List. Be guided by any inclusion or exclusions terms, notes or other instructions such as ‘code first’ and ‘use additional code,’ that would direct the use of a different or additional code from that selected in the index for a particular diagnosis, condition, or disease.
- Step 8: Determine whether the code is at the highest level of specificity. Assign three-digit codes (category codes) if there are no four-digit codes within the code category. Assign four-digit codes (subcategory codes) if there are no five-digit codes for that category. Assign five-digit codes (fifth-digit subclassification codes) for those categories where they are available.
- Step 9: Consult the color coding and reimbursement prompts, including the age, sex and Medicare as secondary payer edits. Consult the official ICD-9-CM guidelines for coding and reporting, and refer to the AHA's (American Hospital Association) Coding Clinic for ICD-9-CM for coding guidelines governing the use of specific codes.
- Step 10: Assign the code.”
For many conditions, one needs to refer to a special section titled “Signs, Symptoms and Ill-defined Conditions” of the ICD-9 code to locate signs and symptoms. As stated on page 13 of the Ingenix text: “In addition to the etiology/manifestation convention that requires two codes to fully describe a single condition that affects multiple body systems, there are other single conditions that also require more than one code.”
The widely used CPT (Current Procedural Terminology) code provides a 5-digit code for procedures. These are grouped as “Evaluation and Management, Anesthesiology, Surgery, Radiology, Pathology and Laboratory, Medicine. CPT codes, an established means for designating specific procedures, also have significant shortcomings. As is the case for ICD codes, the CPT coding system lacks the score-based coding that typifies the inventive system. It focuses on procedures rather than diagnoses; and, for many of its codes, CPT coding ignores severity of the precipitating patient illness, the potential multi-system effects of surgery (which, as shown in FIG. 11 , may be greater on a system other than that with the underlying surgical pathology—e.g., RESP after an large abdominal incision) and the nature and severity of comorbidities (problems not directly related to the planned procedure but which may impact significantly on the patient's ability to withstand the demands of a procedure such as invasive surgery or the need for/effectiveness of additional diagnosis and therapy.
The lack of a uniform language and code is evident at a major institution about which the author is very familiar. The operating room scheduling system captures the CPT code and anesthesiologists bill according to Relative Value Units, which are based upon CPT codes; but many surgical offices use the ICD-9 disease code, the NSQIP quality assurance program uses specified text entries (or their equivalent), government-mandated Surgical Care Improvement Program (SCIP) measures rely upon ICD-9 codes, and hospital billing has relied upon ICD-9 procedure codes (and a system for crosswalk to establish compatible codes). Each coding system has its coding specialists.
With the foregoing in mind, an improved method and system for perioperative evaluation and communication is required that overcomes the limitations of the prior art, including:
-
- lack of a coding and scoring system that provides consistent, suitably detailed, integrated and readily communicable information about multiple aspects of a patient's medical condition, upcoming challenges (e.g., surgery) and related factors; and
- lack of a uniform language, coding system and scoring system for data storage, multiple displays and reports, importing (from other sources), exporting (to multiple diagnostic and treatment algorithms), administrative purposes (quality assurance, resource allocation, and billing) and specific evidence-based research applications.
The present invention provides such a system and method for assessment, quantification and communication and then details a preferred embodiment and adaptations thereof. While the embodiments detailed herein focus primarily on integrated preoperative assessment, it is within the spirit and scope of this invention to focus on and adapt individual components for assessment in other contexts such as longterm care and management in other acute (e.g., emergency, battlefield, or intensive care) settings as well as for triaging and transferring care among healthcare providers in those contexts. Likewise, a patient may followed at standard intervals during long-term care, with additional assessments as deemed indicated, and with more frequent serial assessments during acute challenges or initiations of new therapies. As detailed later in this disclosure, score-driven communication not only would be of great value for perioperative healthcare providers but at virtually every exchange of information among healthcare providers and between healthcare providers and their patients.
It is, therefore, an object of the present invention to provide a multi-dimensional system for assessing, coding, quantifying, displaying, integrating and communicating information relating to patient health and perioperative risk. The system includes a mechanism for inputting patient information and providing an output relating to the patient health and perioperative risk. The output includes a score for the physical condition of the patient, a score for the degree of expected surgical risk and invasiveness, a score for other vital assessments of perioperative complexity, and alphanumeric codes for other factors that may require special preoperative preparation and planning.
It is also an object of the present invention to provide a method for providing an integrative mechanism of quantitative assessment and communication. The method includes inputting patient information, processing the patient information and providing an output relating to patient health and perioperative risk. The output includes a score for the physical condition of the patient, a score for the degree of expected surgical risk and invasiveness, a score for other vital assessments of perioperative complexity and alphanumeric codes for other factors that may require special preoperative preparation and planning.
Other objects and advantages of the present invention will become apparent from the following detailed description when viewed in conjunction with the accompanying drawings, which set forth certain embodiments of the invention.

The detailed embodiments of the present invention are disclosed herein. It should be understood, however, that the disclosed embodiments are merely exemplary of the invention, which may be embodied in various forms. Therefore, the details disclosed herein are not to be interpreted as limiting, but merely as the basis for teaching one skilled in the art how to make and/or use the invention.
Referring to the various Tables and Figures accompanying the present disclosure, a multi-dimensional system and method for assessing, consistently coding, quantifying, displaying, integrating and communicating information relating to patient health and perioperative risk that addresses each of the factors described above is disclosed. Namely, the present system and method provides for (1) a new score for the physical condition of the patient; (2) a score for the degree of expected surgical risk and invasiveness; and other vital assessments of perioperative complexity, including scores for potential airway difficulty—(3) physical factors primarily affecting ventilation and (4) intubation-related factors—; and (5) letter codes with optional scoring for risk indicators and other factors that may require special preoperative preparation and planning (although letter codes or disclosed for (5) in accordance with a preferred embodiment, a variety of alphanumeric codes are contemplated for use in accordance with the present invention). In addition, the present invention introduces subsequently derived scores which expand upon patient condition and integrates these with other perioperative issues such as surgical risk and invasiveness. The heretofore unavailable mechanisms for assessing the multiple aspects of a patient's health described herein provides a common language, a common mechanism of coding and a common mechanism of scoring a patient's health and, in accordance with preferred embodiments detailed herein, enable calculations to assess his/her ability to withstand surgery. The branched-chain logic (shown in multiple figures and detailed below) and associated coding and scoring are consistent among bodily systems and conditions, thereby providing unique simplicity, consistency, and adaptability. The present system further provides for score-driven co-population and export, which focuses the transfer of relevant information.
As those skilled in the art will certainly appreciate, and with reference to FIG. 2 , the present system 10 provides for a mechanism for inputting patient information and providing an output relating to the patient health and perioperative risk. This is implemented via a computer based system linking a variety of data source(s) 12, which cumulatively represent a database 13 of information, with data input mechanisms 14 (for example, computer stations 16 with a graphical user interface 18) for inputting relevant data to the system 10 as described below in greater detail and output displays 20 (for example, computer stations 22 with a graphical user interface 24) for retrieving desired information generated in accordance with a preferred embodiment. The present system may be limited to use at a single site or link a variety of health care facilities in a highly integrated network. The various data sources 12, input mechanisms 14 and output displays 20 are provided with well known processors 26 employed to coordinating the retrieval, processing and outputting of information in accordance with the present invention. As those skilled in the art will also certainly appreciate, the various components making up the present system may be integrated into a single station from which information is input, processed and output. Similarly, the present system may be configured in more elaborate arrangements with multiple data sources, input mechanisms and output displays, or it may be a stand alone unit.
This present system 10 is implemented by applying a method for providing an integrative mechanism of quantitative assessment and communication. The method includes inputting patient information via the data input mechanism 14, processing the patient information via the various processors 26; providing an output relating to patient health and perioperative risk via the output displays. The output includes a score for the physical condition of the patient, a score for the degree of expected surgical risk and invasiveness, a score for other vital assessments of perioperative complexity, including scores for potential airway difficulty composed of physical factors primarily affecting ventilation and intubation-related factors, and letter codes with optional scoring for risk indicators and other factors that may require special preoperative preparation and planning. The techniques employed in carrying out the present system and method are described below in greater detail. Although the present invention is described herein in a computer based system, those skilled in the art will appreciate it could be implemented in a variety of forms without departing from the spirit of the present invention.
In accordance with a preferred embodiment, the scores for the physical condition of the patient and the degree of expected surgical invasiveness are based upon ranking systems familiar to clinicians. In particular, and in accordance with a simplest embodiment, the physical condition of the patient is identified by the ASA PS of medical condition (which is modified in a unique system-specific basis in more elaborate embodiments in accordance with the spirit of the present disclosure) and the expected degree of surgical invasiveness is provided by an integration of the aforementioned ACC/AHA classification of surgical risk and the Johns Hopkins classification of surgical invasiveness (which is modified in a unique system-specific basis in more elaborate embodiments in accordance with preferred applications of the present system).
The present system offers a methodology with the simplicity of ASA PS 1-5 ranking that will serve clinical, investigative and administrative functions—useful to the clinician developing a plan for perioperative care, to the investigator seeking data for outcomes research and evidence-based guidelines, and to the administrator developing operating room case schedules as well quality assurance, productivity assessments and billing policies. This has led to the present integrative mechanism of quantitative assessment and communication which is disclosed and referenced herein under the acronym “SHAPE™” (Silverman-Holt Aggregate Preoperative Evaluation and, for more general applications, Silverman-Holt Aggregate Patient Evaluation). Among its components, SHAPE™ provides a mechanism for communicating and displaying vital information (see FIGS. 3-6 ).
The acronym ASPIRIN™ (ASA physical status, Surgical risk/invasiveness, Physical factors primarily affecting ventilation, Intubation predictors, Risk Indicators that identify items of potential anesthesia-related concern) is used in conveying the various components making up a SHAPE™ score. When employed within computer-based systems, the acronym ASPIRIN™ can be easily expanded so that the last two letters relate Interim Information & Issues, (Information and issues pending, as well as information which may have arrived since the original note was completed or last updated) and Needs that should be addressed (e.g., equipment, missing information, need for special medications such as preoperative antibiotics) (see FIGS. 3-7 ). The sequential scores are consistent with other alphanumerics in clinical medicine, including, but not limited to, “T#N#M#” to represent tumor size, nodes and metastases, and “G#P#” to represent the number of times a woman has been gravid and the number of pregnancies that resulted in live birth at >20 wks. However, and in contrast to prior clinical medicine scoring systems, ASPIRIN™ integrates varied characteristics that may otherwise be unrelated to one another (as opposed to aspects of a given condition) and that themselves may be integrative assessments as opposed to an objective measurement. In accordance with an alternate embodiment, ASPIRIN™ also may be changed to ASPIRING™, wherein the “G” stands for gas and thereby relates the anesthesia plan.
The SHAPE™ scores simply can be displayed (FIGS. 3-7 ) and/or integrated to generate patient condition and surgical invasiveness sums, products or other arithmetic functions, with derived indices, including, for example, those detailed herein (lower portion of FIG. 3 ). The details and applications of the present system and method are presented below. Its advantages have been summarized in Table 2 and are detailed throughout the present disclosure.

Where the SHAPE™ ASPIRIN™ acronym is displayed electronically (for example, on a graphical user interface of a computer system), then clicking a component (e.g., the first number or the first body system in the modified ASA score) can activate a dropdown menu. FIG. 6 shows some of the information that may be available and accessible. A preferred embodiment entails the provision of progressive specificity. For example, this may be achieved by a listing of positive body systems (with scores in descending order); identification of positive aspects of the body system by clicking on the given body system; or jumps to sections of the display (or other aspects of the program) co-populated with the given feature
It should be noted that anesthesiologists often disagree as to whether certain relatively minor risk factors and features constitute justification for a score of “2” (as opposed to “1”). Examples are included in FIG. 32 . In a preferred embodiment, SHAPE™ enables their selection and storage with a 1.5 score—without the need to complicate the SHAPE™ ASPIRIN™ display or clinical SHAPE™ indices (i.e., simply consider them a “1” for display purposes)
In this same spirit, an alternative embodiment entails modifying the 1-5 score to a 0-5 score, with 0=perfectly healthy, 1=presence of risk factors without significant signs or symptoms (2, 3, 4 and 5 would remain unchanged). It is an objective of the present invention that a uniform or consistent scoring system be introduced for each of the SHAPE™ database components and ASPIRIN™ display components. In accordance with a preferred embodiment, a 0 to 5 score is recommended for each component. However, and so as to remain consistent with anesthesiologists' logic during the initial presentation of the present invention, the 1-5 ASA score has been maintained and 1.5 has simply been inserted for most examples herein.
Additionally, other scoring systems may be employed within the scope and spirit of this invention. This may be achieved by converting other quantitative or qualitative measures to the 1-5 or 0-5 scores described above. Alternatively, a different graded range may be utilized (e.g., 0=none, 1=mild, 2=moderate, 3=severe) so long as consistency of scoring among components is maintained.
Assessment of Physical Status
As detailed later in this document, the SHAPE™ text, code and inventive score can be applied to chronic as well as acute conditions and local as well as systemic effects. The embodiments described below will focus on systemic effects in the (acute) perioperative period.
ASA Physical Status. Because of its time-tested clinical utility, the ASA PS classification system has been chosen for use as the foundation for the present SHAPE™ representation of patient condition. However, in order to provide additional depth of information, while not forsaking its simple elegance, the present invention introduces the practice of assigning a 1 to 5 (or 0 to 5) severity score for each major organ system based on information learned from the patient history and physical examination and associated testing. The inventive system further provides the methods and algorithms to do so, thereby generating what is termed herein SHAPE™ Individual Systems Status (SISS™ or SIS™) scores (Table 3 and FIG. 32 ). The scoring criteria for each body system parallel the overall ASA PS classification but, by being body system-specific, are uniquely different and enable quantification of the ability of the given body system (for example, cardiac or respiratory) to withstand potential surgery-induced demands and insults—what is referred to herein as a SHAPE™ assessment of resilience.

In its simplest application, a user may simply score his/her entries of data for each body system—in accordance with the partial display of scored features and subfeatures that are included in FIG. 32—during the history and physical examination. As shown below, in an automated application, items such as those in FIG. 32 may be hard-coded along with their score for selection by the user—when possible without compromising simplicity, scoring is based upon entries at the feature or subfeature level. This may entail a listing of scored features and subfeatures as in FIG. 32 . The details of the branched-chain logic that is employed in preferred embodiments is shown in FIGS. 8A-C and 9A-C and discussed and disclosed later in this document. Even when such detailed branched-chain logic is not evident, it is functioning and accessible in most preferred embodiments; for example, the coding of each item in FIG. 32 and delineated in FIGS. 32.1 and 32.2 is based on branched chain consisting proximally of system, subsystem and feature category codes. Except for the simplest option wherein scoring for each body system (e.g., Central Nervous System, Cardiac System) is based on the user entering a physical status score for each body system in the absence of scoring of individual features or subfeatures, the SHAPE™ methodology is implemented so that scorable choices (e.g., features and/or subfeatures) generate the proximal (e.g., system) score.
Options for arranging items are summarized as follows: 1) Grouping features within each body system or subsystem or feature category according to their default score (with an option to change that score for a given feature in a given patient) as shown in tabular form in FIG. 32 and as listed on user screens (Tables 12, 13, 14 and 16) which are described later in this document; 2) Grouping by any number of alternative means within a system, subsystem or feature category, including sequence of questioning while obtaining a history and sequential order of questions in a questionnaire. 3) Grouping of signs and symptoms based on clinical patterns. 4) Simply listing items in alphabetical order or in numerical sequence based on their respective codes. Again, scoring accompanies item selection as may be facilitated by providing a default score and the option to change a score for each individual item.
The multiple potential actions are summarized in Table 4.

As detailed throughout this disclosure, major aspects of the present invention are the score-driven displays and scripts based upon SISS™ and related scores. For purposes of communication, and in accordance with a preferred embodiment of the present invention, the present invention enables that, for patients with conditions that warrant an ASA PS≧3, a code (for example, first letter or first few letters of the given system) be superscripted to the traditional ASA PS score to indicate the affected organ body system(s). For example, a patient with exertional angina, but no other major medical conditions, would be an ASA 3CARD (for Cardiac), while a patient with long-standing insulin-dependent diabetes mellitus would receive an ASA 3ENDO (for Endocrine). If there are abnormalities of multiple systems, these would be represented by each of the appropriate system identifications. Thus, a patient with exertional angina and insulin-dependent diabetes would be an ASA 3CARD,ENDO. In cases where multi-system ASA≧3 disease of differing clinical severity exists, the numerical score(s) that is (are) represented simply could be the system(s) with the highest score. Thus, a patient with cardiogenic pulmonary edema (worthy of an ASA 4 designation) and insulin-dependent diabetes (worthy of an ASA 3 designation) could be represented as an ASA 4CARD. Alternatively, ASA4CARD>ENDO or ASA 4CARD3ENDO could be used to designate both the ASA 4 and the ASA 3 disorders. Comparable annotation is shown in FIG. 4 (showing inventive components at the end of an inventive care giver note) and FIGS. 6 and 7 (showing examples of a potential ASPIRIN™ display), which demonstrate some of the increased information (vs. traditional listings on an operating room schedule) that may be generated and used for co-population of other portions of the inventive program or exported for other applications. It would be within the spirit and scope of this invention to have other mechanisms of #-systems display (e.g., systems in parentheses as opposed to as superscripts) as well as to list the systems followed by their score. For purposes of a consolidated meaningful display, it is believed that the illustrated embodiments are most effective.
The clinical importance of such system-specific data is suggested by recent data collected by my research team for presentation at the 2006 Annual Meeting of the American Society of Anesthesiologists. Of 220 patients with ASA 3 or 4 physical status, the Cardiac system was the most commonly reported system to merit such a score; this was followed by the Central Nervous System and Respiratory System. In addition, 30.4% of these patients had two systems with grade 3 or 4 level of dysfunction, 14.1% had three such systems and 2.1% had four or more such systems.
It thus should be evident that the system-specific scoring introduced herein looks at the overall ASA physical status score as being derived from the scores assigned to individual body systems (with the potential to override this score). These in turn are based upon the highest score(s) assigned to signs, symptoms and/or test results within the given body system (SISS™), typically at the feature or subfeature level. This constitutes a preferred embodiment; however, other means of consistent assignment and management of scores are within the spirit and scope of this invention.
Essentials of Coding and Scoring in Preferred Embodiments:
There are multiple options for coding and scoring data base components; these will be delineated here with respect to SISS™ components. The present invention would make a significant impact simply by adding on the scoring component provided by SISS™ (and SICU™ and SASRI™) to systems and/or systems and their component features. However, the introduction of coding and scoring based upon the branched-chain logic described herein provides a unique foundation for electronic record keeping and contributes significantly to the advantages summarized in Table 2.
In most of the embodiments shown herein, there is consistent progression from system (S) to subsystem (sS) to feature category (FC) to scored features (F) and/or scored subfeatures (sF) and unscored descriptors (D). Several different means of coding and display are shown in order to illustrate the diversity of techniques that are within the spirit and scope of this invention, but also to consolidate selected displays (e.g., FIG. 9 c) and to delineate means of co-population and code integration (e.g., FIG. 14 ). The essential aspects of a preferred embodiment are summarized in Table 6.

The embodiment of Table 6 is shown in FIGS. 8C and 9C . Alternative embodiments, relying on equivalent S, sS, FC, F, sF, and D progression are shown in FIGS. 8A , 8B, 9A and 9B. A sample step-by-step process for data entry in accordance with this branched-logic mechanism is detailed later in this disclosure with reference to FIGS. 26-31 .
Critical aspects of the preferred embodiment shown in FIGS. 8C and 9C include:
-
- 1. Primary scoring of features (F) and subfeatures (sF) where each F and sF has a score. If, however, F is followed by an sF, the score for sF predominates and default score for F becomes the score assigned to the sF. For example, a feature such as “recent myocardial infarction” may be followed by the subfeature “6 months ago, stable ($3)” or by the subfeatures “last week ($4)” and “persistent abnormal wall motion ($4).”
- 2. Progressive coding in association with branched-chain logic with the following unique establishment of fixed and variable code & score components:
- A fixed code for a given item's feature category/feature/subfeature(s) that, in preferred embodiments, remains with the item no matter what aspects of the database or interfaced database it co-populates (unless designated differently by the user).
- A variable proximal portion of the code which is specific for the given bodily system (e.g., Cardiac) and subsystem (e.g., Ischemic Heart Disease) or their equivalent [e.g., wherein the invention treats a grouping such as a Risk indicator as a “system” (discussed in subsequent section of this disclosure).
- An optional prefix.
- An optional suffix.
As will be shown later, the present invention also facilitates uniquely consistent and universal coding for exporting to and integration with other databases.
-
- Options for integrating with compatible databases, with adaptable prefixes and/or suffixes and integrated scoring as above (as discussed below in greater detail).
- Options for importing from programs with otherwise incompatible codes and scores or exporting to them (as discussed below in greater detail).
A key advantage of the present invention is that it accomplishes the coding and scoring without “getting in the way.” The carefully configured branched logic further allows such processes to be relatively seamless and transparent. The text, code and score conversion index and dictionary allows for automated translation and universality. Instead of requiring repetitive progression down each branch, the present invention provides for default jumps (if a body system is negative) and provides options that obviate the need for user delineation of S/sS/FC/F/sF . . . . For example, a consolidated display of what some might consider all systems and subsystems—configured to enable options for each subsystem to be viewed on a single screen—is shown in FIG. 32 . FIGS. 32.1 and 32.2 indicate that, although not visible during data entry, each of the scored items is associated with a body system, subsystem and feature category coding. Additionally, FIG. 32 does not distinguish between F and sF (since they are coded and scored comparably). Items are worded to be user friendly and may actually represent more than one F or F+sF; this would be evident in storage within the database and thereby enable searches based on individual as well as combined features and subfeatures.
Whereas preferred embodiments of the present invention distinguish between scored features and subfeatures vs. unscored descriptors, the user may also elect to select the information provided by a feature but to bypass the prompt to assign the default score or to select a score. That is, the user may select the item without its score. This may offer the advantage of allowing for a more speedy entry of data, in that once the feature with the highest score is selected for a given body system or subsystem, other choices could be selected without concern about scoring. However, the detailed scoring capabilities of the present invention provide for greater detail, greater consistency, and more robust population of the SHAPE™ database and co-population of other sites (e.g., when data are exported to diagnostic and treatment algorithms and related scripts). Furthermore, unless one changes the default scoring (because of his/her clinical findings), the process of scoring is transparent.
The system-based scoring for each of the body's main systems (as may be listed and modified in FIG. 32 and subsequent tables and figures) is done in large part not only to ensure communication consistent with (and superior to) the basic ASA physical status score described above, but also to take into account that without consolidation into a body system or subsystem score, the range of individually scored features and subfeatures would be unmanageable (perhaps accounting for why, to the best of my knowledge, heretofore no one has been able to effectively design a highly detailed, integrative system such as that described herein). Borrowing from an old beer commercial, one might say above SISS™—“better accuracy” and “less filling.”
Scores for S, sS, FC, F and sF are represented by $# (as shown in FIGS. 8 and 9 and throughout this disclosure. Descriptors are unique—they provide valuable information but do not significantly affect the severity of the disorder; hence they are not scored. To facilitate their inclusion in the database and accommodate preferences for description terms and expressions, Descriptor codes may be grouped as shown in Table 7.

The clinical importance of such body system-specific data is suggested by recent data collected by my research team for presentation at the 2006 Annual Meeting of the American Society of Anesthesiologists. Of 220 patients with ASA 3 or 4 physical status, the Cardiac system was the most commonly reported body system to merit such a score; this was followed by the Central Nervous System and Respiratory System. In addition, 30.4% of these patients had two body systems with grade 3 or 4 level of dysfunction, 14.1% had three such body systems and 2.1% had four or more such body systems.
It thus should be evident that the body system-specific scoring introduced herein looks at the overall ASA physical status score as being derived from the scores assigned to individual body systems (with the potential to override this score). These in turn are based upon the highest score(s) assigned to signs, symptoms and/or test results within the given body system (SISS™), typically at the feature or subfeature level. This constitutes a preferred embodiment; however, other mechanisms of consistent assignment and management of scores are within the spirit and scope of this invention. As noted above, scored features or subfeatures are within a feature category of a given subsystem, which is, in turn, a part of a body system (such as CARDIAC).
Co-population and exporting may be at any of the aforementioned levels of branching. When a given item co-populates more than one system, its FC/F/sF (and possibly D) code remains fixed while the S/sS portion of the code changes (as shown in Table 6). The distinction between body systems and subsystems should not be considered absolute or restrictive when applied to the present invention; but once a decision is made it should be maintained so as to ensure consistent coding. Thus, even though it is a specific condition, diabetes is coded as subsystem and treated as such in applications of the program (e.g., co-population and exporting).
Cumulative Scores
The ensuing sections will expand upon the present invention by describing:
1. Other aspects of SISS™ as they relate to scoring and coding
2. Describing the unique far-reaching, multifactorial yet uniform nature of the inventive program.
The SISS™ scoring permits cumulative scoring based upon the number of disorders (as may be ascertained from the number of positive feature categories) or diseased body systems and their degree of dysfunction in what is called herein the SHAPE™ Aggregate Disorders (SAD™) score (FIG. 3 ).
Among its many applications is the integration of clinical findings and test results. For example, the provisions for integrated details afforded by the present invention uniquely enable one to overcome the problem of introducing excessive subjectivity and potential bias when viewing findings in the context of other conditions and risk factors. For example, nonspecific ST-T (NSST) wave changes on an EKG likely would be dismissed as not clinically significant in an otherwise healthy individual without significant risk factors for coronary artery disease. However, they might prompt a cardiology evaluation (and stress test) in the presence of clinical findings or risk factors. The present invention offers potential ways for a healthcare provider or institution to address this issue:
-
- List scenarios that constitute
class 2 andclass 3 findings (as shown for CARDIACEKG inFIG. 32 ); however, a complete list of modifiers may be exhaustive and, at times, inconclusive. - Simply score the EKG finding as
class 2 but automatically convert it to class 3 (which may be annotated to indicate that it has been increased as a result of integrating factors as with the symbol “Σ3”) if selective factors exceed a certain cutoff; i.e., if the nonspecific risk factors and indicators for ischemic heart disease (under CARDIAC inFIG. 32 ) exceed a score of 2 or summate to an established cutoff. This score-driven means of basing a decision on objective criteria minimizes the current likelihood of bias that may be introduced if one simply has to make the decision that the presumed importance of the EKG should be increased because of “likely significant clinical factors.” - Don't worry about the score for EKG; simply cumulate scores from relevant systems, subsystems and/or feature categories to determine score-driven actions.
- List scenarios that constitute
Certain issues that have been taken into account for implementing the current method(s) for scoring and cumulating multiple body systems in the present invention include:
-
- a) ensuring identification and appropriate cumulation when more than one body system has a given score (e.g., CNS, CARD and RESP all receive a score of 3).
- b) preventing indiscriminant cumulation by simply adding scores such that three body systems with a score of 2 generate a higher cumulative than a single system with a score of 4 (which virtually all would agree constitutes a degree of illness more severe than three body systems with a score of 2).
These issues may be addressed in a number of ways. Multiple body systems with the same score (for different disorders) may be identified at the end of the History and Physical (FIG. 4 ) or as by superscripts in the ASPIRIN™ display (FIGS. 6 , 7B, and 7C). If the user wishes to determine a cumulative index such as SAD™, the present invention enables assignment of an incremental value to the “modified ASA score” when there are multiple body systems that warrant a given score. For example, if both cardiac and respiratory systems were scored 3, then one could assign a cumulative score of 3.2 or 32 (in accordance with a preferred embodiment, the decimal or superscript has been elected to reflect the number of body systems). If three body systems were scored 3, this could be represented as 3.3 or 33. An alternative embodiment entails adding 0.2 for each additional ASA 4 body system and 0.1 for each additional ASA 3 body system. Alternatively, if one wishes to avoid a situation where an individual with three “2's” or two “3's” is assigned a higher cumulative score than an individual with a “4” (in that almost all would agree that the individual with the “4” is far sicker), one can use a formula (i.e., a correction factor) to reduce the impact when multiple body systems are assigned the same score. As for other aspects of the invention, the abundance of potential data integration and analysis can be generated from the “routine” entry of clinical data.
An alternative embodiment for scoring (regardless of the number of body systems entails conversion of the ordinal 1-5 scores to points which are reflective of relative illness and impact. For example, based on analyses of data from the initial applications (described above), preferred embodiments will enable 1-5 scores to be converted to points that take into account the dramatic rises in morbidity, length of stays and costs at greater degrees of illness (e.g., 2→2, 3→7, and 4→25 points). Comparable points may be assigned to the 1-5 surgical scores.
Thus, for example, scores of 3 for CARD and ENDO could provide a variety of SAD™ scoring options including: 6 (simple addition), 3.2 (modified for multiple systems), 14 (addition of 7+7 points), 7.6 (points modified for multiple systems).
Managing Scores and Codes for Disorders Affecting Multiple Body Systems:
The present invention is also designed to address two related vital issues—what to when a disorder of one body system also affects another body system or when more than one system is affected by a “Multisystem” condition. Ways in which this is accomplished by the present invention include:
-
- a) providing a mechanism for designating whether multiple body systems affected by a given multisystem disorder such as those listed at the bottom of
FIG. 32 should be scored independently or dependently - b) providing a mechanism for designating whether the scores for a body system that is affected by another body system should be cumulated.
- a) providing a mechanism for designating whether multiple body systems affected by a given multisystem disorder such as those listed at the bottom of
Preferred embodiments of the present invention address these in the following manner. When a feature or subfeature that is found in more than one body system (i.e., it constitute a disorder of more than one body system), SHAPE™ provides the following:
-
- Codes with identical fixed FC/F/sF . . . portions of the code populate each site, with different variable S/sS portions.
- Identification of what generally is the predominant system (documented with the system # at the beginning of the “FC” code that groups and identifies all feature categories within a given system) regardless of where the item currently lies.
- Easy access to the body system and body subsystem of a given F or F/sF by clicking on the feature or subfeature to display the proximal S/sS/FC pathway.
- Option to include combination system codes in the variable portion of the code with the designations of relative importance and directionality shown in Table 8 (below).
The invention provides a mechanism for designating scores for each of the body systems associated with a given feature or subfeature. Where two or more specific body systems are involved, unless otherwise specified by the user (see below), overlapping information would impact on the score of each system and both would be included in an inventive cumulative score, such as, SAD™. Examples of such interactions include:
-
- a) Endstage Renal injury as a result of Hypertension—some or all of the Renal system score would be due to hypertension-induced renal injury; some or all of the Hypertension score would be due to its systemic impact on the kidney.
- b) If a patient has vomiting which leads to a fluid and electrolyte disturbance, then both the GI system and the Fluid & Lytes system would reflect the conditions. Since they otherwise are independent systems, both likely would be included in a cumulative SAD™ score. In support of this decision, correction of the Fluid & Lytes problem would not necessarily affect vomiting; likewise, if vomiting suddenly stopped, it is likely the Fluid & Lytes problem would require significantly more time to resolve and might require separate therapy. (While in preferred embodiments the systemic impact score for F and sF would be the same in both systems, the local impact score may differ and the overall system scores may differ (depending on other F and sF).
Once the healthcare provider has reached the FC level for an item affecting multiple body systems, he/she may elect to continue within the given body system or jump to the system primarily affected by the disorder since this would likely have more hard-coded F, sF and ssF. In many cases, the computer will automatically jump but will give the user the option of determining how to weight the different systems (Table 8).

Combined Code
Multisystem disorders present particularly challenges in that they do not necessarily have their own body “system.” In preferred embodiments, the Multisystem paradigms can be accessed by the following means:
-
- Selecting “Multisystem Disorder” as if it were a specific body system. This then jumps to a screen that allows one to select from Multisystem Disorder categories such as those listed at the end of
FIG. 32 (specifically,FIG. 32.18 ) (or to type-in). The next screen would list the Multisystem Disorders within the selected category. Then, the user is prompted to select information about the given disorder and/or select specific body systems that are affected. The computer then jumps to the selected screens which are completed in routine fashion with the addition of the checklist shown in Table 9. The code for entries into the body system is then modified to reflect that the body system is affected by a Multisystem Disorder (as may be accomplished by including the Greek letter [shown at the bottom ofFIG. 32.18 ] followed by a number as a prefix to the body system code). - Proceeding normally through the Review of Systems until one reaches a body system that is affected by a Multisystem Disorder. A “Multisystem Disorder” option is provided within each system; selecting it will initiate a series of steps comparable to those noted above.
- Selecting “Multisystem Disorder” as if it were a specific body system. This then jumps to a screen that allows one to select from Multisystem Disorder categories such as those listed at the end of

Table 9 includes a prompt to define a “Weighting Code (vs. Multisystem Disorder) for each body system affected by the Multiystem Disorder. This addresses a major issue that otherwise can plague a data entry program. When a specific body system (e.g. “Cardiac”) is affected by a multisystem condition (e.g., “Amyloidosis”), the interaction is more complex than between two specific body systems because the user must determine if the multisystem condition's systemic impact is:
-
- solely due to its effect on Cardiac (—could be designated “=” in one of the multiple potential forms of dual-system designation that are consistent with the inventive system);
- due to multiple effects on specific body systems, none of which merits a greater score than its cited effects on the Cardiac system (—could be designated as “+”); or
- due to factors wherein the multisystem disorder may have greater overall systemic impact than the effects cited for specific body systems such as Cardiac (—could be designated as “+>”). An example might be supermorbid obesity (typically assigned a score of 3) without significant organ dysfunction; the multisystem condition in and of itself may have significant impact during and after surgery. Likewise, fulminant amyloidosis may receive a higher score than its current manifestations on specific systems.
Unless otherwise specified, the systems affected by multiple conditions annotated with a “+” or “+>” would be included in a cumulative SAD™ score.
Events Such as Surgery
SHAPE™'s text, code and inventive score can be applied to the impact of a variety of challenges and interventions, including surgery, trauma, and therapies. Consistent with the focus on embodiments addressing perioperative concerns, the embodiments described below will focus on the impact of surgery.
Surgical Risk & Invasiveness: To be consistent with the 5-point ASA PS system, a five tiered classification scheme is used for ranking of surgical risk and invasiveness (or SHAPE™ Overall Cutting Upset (SOCU™)) as identified in the second letter in ASPIRIN™ (S) as described above in accordance with the present invention (See Table 10a). The lowest risk score of 1 would be appropriate for superficial procedures such as a breast biopsy which may require minimal sedation (comparable to the “low-risk” classifications of the ACC/AHA Guidelines and the “minimally invasive” class of Pasternak rankings). A score of 5 is assigned to highly invasive intrathoracic and intracranial procedures, those associated with massive blood loss (>1500 mL) as well as any emergent major operation (consistent with the ACC/AHA Guidelines “high-risk” classification and Pasternak's most invasive category). Scores of 2 through 4 represent the spectrum of risk between these two extremes. Since it has been concluded that the “intermediate” ranking of the ACC/AHA was too broad, it has been subdivided, in accordance with a preferred embodiment of the present invention, in accordance with the surgical invasiveness score proposed by Pasternak as well as by taking into consideration anesthetic requirements and the potential for otherwise unsuspected pulmonary or hemodynamic changes. Conversely, the score proposed by Pasternak is not consistently translatable to the low, intermediate- and high-risk ACC/AHA classifications and thus not readily applicable to established risk assessment indices and therapeutic guidelines, which include the ACC/AHA classification as to when consultation with a cardiologist is indicated prior to surgery. The 1-5 score of overall surgical risk and invasiveness (referred to as the SHAPE™ Overall Cutting Upset or SOCU™ [pronounced “sock you”] score) introduced herein is designed to provide greater precision and greater relevance to perioperative events than the ACC/AHA classifications, while maintaining compatibility with indices and guidelines that utilize the ACC/AHA classifications. In accordance with the proposed 0-5 ASA physical status score, SOCU™ would have 0=no procedure.
The integration of the 1-5 gradations of patient condition and risk/invasiveness has been evaluated in 878 patients by the inventor and colleagues at his institution (FIG. 1 ) and enabled creation of models that predict a substantial portion of the variation in hospital charges, length of stay, and anesthesia billing units. Both factors were positively correlated with each of the three outcome variables. For hospital LOS (length of stay), the maximum amount of variation that could be derived from knowledge of both factors was 56.7%; this was possible by defining an index equal to 0.3(ASA PS)+0.7(SOCU™). For hospital charges, the maximum amount of variation predicted by ASA PS and SOCU™ was 45.0% when an index equal to 0.35(ASA PS)+0.56(SOCU™) was used. Although both ASA PS and SOCU™ were positively correlated with anesthesia billing units and had independent predictive value, in combination, only the impact of SOCU™ was statistically significant, predicting 68.0% of the variation. (Note, this is a derivation data set that has not yet been validated in a prospective study). Moreover, the data confirm that while helpful, simply looking at the “A” and the “S” of ASPIRIN™ is not sufficient.
Another unique inventive feature is the body system-specific coding and scoring of the surgical risk/invasiveness score in a manner comparable to that for the inventive SISS™ score of patient condition. The inventive SHAPE™ Intersystem Cutting Upset (SICU™) score is employed in accordance with the present invention to delineate the inter-system impact of the planned surgical procedure regardless of the patient's underlying condition (DIFF). As per recording, communication and display based on SISS™, the body systems which are likely to be affected by the given surgery based on SICU™ can be documented for the SHAPE™ database and those likely to be most severely affected can be annotated in the ASPIRIN™ display. That is, those scored ≧3 can be cited as superscripts after the second number (corresponding to “S” for surgical risk and invasiveness) in the display. A representative embodiment for the SICU™ scoring is provided in Table 10b and shown in FIGS. 6B and 7C . Unless noted to be otherwise, the SICU™ score is based on the potential upset of each body system's role in maintaining overall patient condition (i.e., its overall systemic effect). Hence, it is possible that a vital body system such as Respiratory may receive a higher SICU™ score than the body system actually undergoing the given surgery; e.g., if a large incision is required to removal an intraabdominal mass and there is subsequent pain and compromised breathing. Additionally, removal of a kidney from someone who already requires dialysis may receive a lower KUBU (kidney, ureter, bladder, and urethra) score than less extreme renal surgery on someone whose kidneys still are functional (since the change from normal function to decreased function in the latter is of greater systemic impact). Likewise, a patient with a sarcoma of the leg may be assigned a higher score for systemic impact than an individual who underwent amputation and has remained tumor-free. Alternatively, as will be detailed later for disorders, the inventive system can be modified to score local as well as systemic impacts of an intervention such as surgery. In which case, SICU™ score likely would be higher at the site of the surgery.

Procedures that consistently are amenable to local and/or conscious sedation (e.g., extracorporeal shock wave lithotripsy) have been annotated with an “L,” in that they likely would not be influenced by anesthesia-related factors such as a difficult airway. Although qualifying as “minor” or “low-intermediate,” certain procedures are associated with features that may disproportionately influence their effects on outcome variables such as length of stay and total hospital costs independent of surgical risk/invasiveness; examples, which have been annotated with a “ ,” include those requiring postoperative intravenous antibiotics because of hardware insertion or prolonged observation to ensure flap viability, surgical effectiveness, or device functioning. In such cases, the effect of coexisting morbidities on length of stay and costs may need to take into account obligatory lengths of stay. |

Together, the itemized body system scores for patient condition (SISS™) and surgical impact (SICU™) provide a heretofore unavailable:
-
- Mechanisms for more effective prediction and assessment of the ability of specific body systems to meet and withstand the demands of surgery (i.e., SHAPE™ numeric assessment of resilience).
- Mechanisms for communication of such information
- Bases for score-driven body system-specific, as well as general, diagnostic and treatment algorithms (i.e., guidelines for obtaining a cardiology consult and/or when to initiate cardioprotective beta-blocker therapy)
- Accumulation of evidence-based guidelines for specific medical and surgical disorders as well as the myriad applications summarized in Table 2 and
FIGS. 3 and 5
A key feature of the present invention is that it accomplishes this with its unique foundation of itemized scoring—a potential enormous gain for relatively little user effort that does not entail retrospective assessments of variables and assignments of scores.
Other Inventive Scored Assessments: the “PIRIN” of ASPIRIN™
SHAPE™'s text, code and inventive score also can be applied to items which, often because of the given context (e.g., perioperative), constitute a risk or management issue that is disproportionate to—or not reflected by—their “A” or “S” score. The literature is replete with recommendations, some of which are evidence-based, as to how to characterize, plan for and manage what may be termed “non-ASA score, non-surgical invasiveness factors” that affect anesthetic complexity and potentially impact of patient morbidity. However, to the best of my knowledge, a system is lacking for integrating the factors, scoring them in a consistent manner, incorporating them in a consistent communicable relative score, and applying them for score-driven decisions and actions—i.e., for using them in the manner(s) introduced herein.
The embodiments described below focus on anesthesia and overall perioperative concerns. As those skilled in the art will certainly appreciate, comparable indices could be established for other settings.
Physical Factors Primarily Affecting Ventilation & Intubation Predictors:
For anesthesiologists, airway issues are paramount—even if they have minimal impact on daily life—and hence are assigned ASPIRIN™'s “P” (“Physical factors that affect ventilation”) and “I” (“Intubation factors and related issued”) categories and inventive scores as summarized in Tables 11a and 11b and described below.
As discussed below, a letter/alphanumeric scored code is disclosed for other issues that have a potential impact that may be disproportionate to their “A” or “P” relative score. These “Risk indicators (“R” of ASPIRIN™) may generate score-driven communication, preparation and planning based upon an item-specific score or a generalized cutoff (e.g., ≧3).
Physical factors primary affecting ventilation & Intubation predictors: Consistent with the separation of mask ventilation and intubation issues in difficult airway algorithms, the present system opts to provide groupings of “Physical factors affecting ventilation” and “Intubation factors and related issues”. A list of risk factors was garnered from published studies and clinical experience, with an appreciation that, while prior investigators commonly excluded high-risk patient populations, such as obstetrical patients and those with known airway pathology, el-Ganzouri A R, McCarthy R J, Tuman K J, Tanck E N, Ivankovich A D, Preoperative airway assessment: predictive value of a multivariate risk index, Anesth Analg. 1996; 82(6):1197-1204; Langeron 0, Masso E, Huraux C, et al, Prediction of difficult mask ventilation, Anesthesiology 2000; 92(5):1229-1236; Yildiz T S, Solak M, Toker K, The incidence and risk factors of difficult mask ventilation, J. Anesth. 2005; 19(1):7-11; Bellhouse C P, Dore C, Predicting difficult incubation, Br J Anaesth 1989; 62(4)469; Combes X, Le Roux B, Suen P, et al., Unanticipated difficult airway in anesthetized patients: prospective validation of a management algorithm, Anesthesiology 2004; 100(5):1146-50; Tse J C, Rimm E B, Hussain A, Predicting difficult endotracheal incubation in surgical patients scheduled for general anesthesia: a propective blind study, Anesth Analg. 1995; 81(2):254-258; Turkan S, Ates Y, Cuhruk H, Tekdemir I, Should we reevaluate the variables for predicting the difficult airway in anesthesiology?, Anesth Analg. 2002; 94(5):1340-1344; Wilson M E, Spiegelhalter D, Robertson J A, Lesser P, Predicting difficult intubation, Br J Anaesth. 1988; 61(2):211-216; Yamamoto K, Tsubokawa T, Shibata K, Ohmura S, Nitta S, Kobayashi T, Predicting difficult intubation with indirect laryngoscopy, Anesthesiology 1997; 86(2):316-321.} a score designed for integrative assessment and communication would have to account for these patients. Points for each item were tentatively assigned based on perceived impact. The individual factor and cumulative points for both ventilation and intubation are summarized in Tables 11a and 11b (collectively referred to as Table 4), with the realization that factors often overlap.
As noted in Tables 11a and 11b, it is possible to accumulate a score greater than 5 for the “Physical factors affecting ventilation” and “Intubation factors and related issues” groupings. The actual total, as well as the components, may prove valuable for quality assurance, outcome, and resource studies. In accordance with a preferred embodiment of the present invention, 5 has been tentatively set as a cutoff, so as to establish a level where most anesthesiologists would agree that there is sufficient concern to notify all parties as to the need for careful reassessment and planning (for example, availability of equipment for possible fiberoptic intubation, appropriate allocation of time and staffing). In addition, assigning a five-point scale maintains the consistency of the scoring system for patient condition (modified ASA class) and surgical risk (modified ACC/AHA class). The actual data are stored in the database for subsequent applications as well as to provide greater information to the patient's caregivers. Table 11. Factors likely to affect airway management, divided for purposes of presentation into “Physical factors which affect mask ventilation” (4a) and “Intubation predictors” (4b). For each table, scores from each of the five categories are summated score >5 may simply be displayed as a 5. A score of this magnitude should alert the O.R. team to the potential need for special planning.

Other Risk Indicators—Anesthetic Risk—Letter Code for Risk Indicators. Even with the inclusion of an airway risk score, the combination of modified ASA physical status and surgical risk still fails to address certain conditions that may pose additional risk or added complexity to anesthetic/perioperative management. These “Risk indicators” include anesthesia-specific, perioperative-specific, and more general conditions based upon score-driven population of entries such as Allergies, Medications, Prior Anesthetics, Social Habits, Review of System, Physical Exam and Laboratory reports. As detailed in FIG. 11 and shown in portions of FIGS. 3 , 4, 6, 7C, 20 and 24, a component of the present invention is a letter/alphanumeric scored code for such issues that may have a condition that is disproportionate to their “A” or “P” or “I” relative score. The Risk indicator score that is assigned [SHAPE™ Alphanumeric Score for Risk Indicators (SASRI™)] often depends on the context (e.g., it may be higher for pre-anesthetic care than it would be for chronic medical care). Higher scores provide an indication of potential concerns for the clinicians involved with the patient's care and may be accompanied by a score-driven email notice, phone call or page as may be based upon an item-specific score or a generalized cutoff (e.g., ≧3).
SASRI™ is a major improvement over existing systems wherein the perioperative impact of a clinical condition such as malignant hyperthermia, which does not pose a physical limitation on daily life, is underestimated by the ASA physical status score. Hence, without effective communication, an anesthesiologist may not be aware of this issue until he/she reviews the chart prior to initiating the anesthetic. Even when a disorder would otherwise be evident, the score-driven categorization of specific features by SASRI™ also is central to the value of the inventive Risk indicators. For example, although the risk associated with the underlying medical condition that prompted insertion of a device such as an automatic implantable cardiac defibrillator (AICD) would have been addressed in the assignment of ASA physical status and, more specifically the system-specific ASA status (via SISS™ introduced herein), the presence of an AICD itself (and hence an alert about the need to prepare and plan for it) might not be communicated as effectively in the absence of the Risk indicator.
Examples of scoring Risk indicators are shown in FIG. 11 . The generic SASRI™ scores in FIG. 11 facilitate tabular display but may be supplemented with graded scores that are more specific for a given condition. For example, adverse/allergic reactions to medications may be categorized as:
-
- 1=probably not significant risk factor; 2=potentially significant; if applicable, exposure to trigger should be minimized or avoided (common cutoff for co-population of Interim Information and Issues); 3=potentially significant; may require pretreatment; if applicable, avoid exposure (common cutoff for display); 4=likely significant; may require pretreatment; if applicable, avoid exposure; 5=critical or likely critical risk factor that may not be totally avoided
The precise mechanism varies for different sources of input. For Allergies, when a drug and the accompanying reaction are selected, a default score is provided, with an option (e.g., dropdown menu) to alter that score, consistent with other areas of the inventive program. For issues such as smoking and alcohol, user options include:
-
- selecting the hard-coded options that correspond to the different breakdowns (e.g., 3-4 drinks/day, current).
- entering more specific information (e.g. 3.5 py), which the computer will store to preserve detail but also categorize under “1-5 py” for scoring, reporting, and analyses.
- The healthcare provider is also prompted to rate the severity of the signs and symptoms attributable to smoking (which may be equivalent to (and co-populate) that for the features and subfeatures selected under the “RESPIRATORY” system).
The Risk indicator score that is assigned [SHAPE™ Alphanumeric Score for Risk Indicators (SASRI™)] often depends on the context (e.g., it may be higher for pre-anesthetic care than it would be for chronic medical care).
-
- Because the score assigned to Risk indicators takes into account the subclinical impact of risk factors and the impending impact of surgery, a given feature may have a higher SASRI™ than SISS™ score—e.g., cigarette smoking (which has the potential to have serious insidious impact before causing comparable signs and symptoms).
- The risk of aspiration pulmonary aspiration of gastric contents is of a magnitude in the perioperative period that it is worth documenting with a SASRI™ score, even though it already is partly addressed in the Physical factors affecting mask ventilation score.
- Potentially dangerous abnormal laboratory test results (which are graded on a test-by-test basis as shown in
FIG. 17 can be grouped under this heading to facilitate a last-minute review of critical data (as opposed to simply being listed under “Laboratory Tests”). - Medications that need to be changed in the context of an upcoming challenge such as surgery. When medications are entered during the basic history and physical or via an alternative form of data entry (e.g., patient questionnaire), predetermined medications would co-populate one of the series of “potentially worrisome meds” screens. The assigned default score relates information as to the likely nature and severity of the issues associated with the given drug (which can be modified). Aspects include:
- Whereas someone could be maintained chronically on aspirin and Plavix, continuation of these drugs has the potential to lead to excessive bleeding during major surgery. Alternatively, discontinuing them prior to surgery likewise may pose risks. These factors, alone or in combination, can generate a risk indicator score that is relatively higher than that in the review of systems. The inclusion of this issue in Risk Indicators alerts care givers to current status and potential concerns. Additionally, based on its score (
FIG. 22 ), it can prompt inclusion of an alert in the “Interim Information & Issues” section of ASPIRIN™ (see below) - The score may integrate entries from more than one aspect of the database (e.g., as for the assessment of the impact of a low potassium level in a patient on digoxin
- SASRI™ can generate score-driven checks and alerts by integrating scores for one or more Risk indicators or combinations of Risk indicators and SISS™ scores.
- Whereas someone could be maintained chronically on aspirin and Plavix, continuation of these drugs has the potential to lead to excessive bleeding during major surgery. Alternatively, discontinuing them prior to surgery likewise may pose risks. These factors, alone or in combination, can generate a risk indicator score that is relatively higher than that in the review of systems. The inclusion of this issue in Risk Indicators alerts care givers to current status and potential concerns. Additionally, based on its score (
Communication and display of Risk indicators can be consistent with the #system or #system display used for SISS™ of FIGS. 4 , 6 and 7, wherein the highest score is listed and the items with scores above a certain cutoff would be listed after the score (with “>” separating the successive scoring tiers). Alternatively, one could simply list all items above a preset cutoff with the option to include the score after the item (e.g., Latex5 or AICD#). These two alternatives are shown in FIGS. 7B and 7C , respectively. In electronic versions, clicking on the # generates a listing of scored Risk indicators
In addition to co-population of Risk indicators at the time of data entry during attainment of the history and physical, there are settings where entries co-populate algorithms for cumulative diagnostic, predictive and treatment algorithms before being converted to a scored Risk Indicator. Potential results of such unique bidirectional exchange are illustrated in FIG. 11 . As is evident for multiple applications of the inventive program, co-population is facilitated by the text, code and score conversion index and dictionary (FIG. 10 ).
In accordance with system/subsystem/feature category/feature . . . coding, in a preferred embodiment, the data shown in FIG. 11 would be stored as Risk indicator/specific grouping/feature category (e.g., alcohol)/scored feature or subfeature. Again consistent with coding for review of body systems described above, the feature category/feature/subfeature . . . components of the code remain intact throughout the database. As noted above, it's possible that the body “system” score assigned for a given item may be different (e.g., higher) for the Risk indicator body “system” than for the body system associated with the original site of data entry; however, in preferred embodiments, the FC/F . . . score remains unchanged. This likewise is maintained for “Interim Information and Issues” as discussed below in greater detail.
Interim Information & Issues (I):
This next component of ASPIRIN™ identifies information and issues that likely will be supplemented after completion of the given entry into the database (e.g., after the given history and physical examination). This may be referred to as “III™, an adaptation of the common ethnic expression when one realizes something important may be missing (“aye, aye, aye”).
While certain entries are obligatory regardless of their score (e.g., a surgically focused history and physical must be in the chart), population of “I” primarily is score-driven, being based upon SISS™, SASRI™ and SICU™ scores (and related indices and score-driven diagnostic and treatment algorithms such as those described herein). Lab tests, for example, would be generated in accordance with guidelines such as those shown in FIGS. 16 , 19 and 20 and listed under “I” accordingly.
The items that populate Interim Information & Issues simply can be identified by name or code. However, in preferred embodiments, the inventive system assigns “I” scores to the entries—on a scale comparable to that for A, S, P, I, and R (e.g., the uniform 0-5 code of FIGS. 17 , 18, 20, and 21 or specific codes tailored to specific entries). A cutoff (e.g., ≧2) may be established to determine which items are displayed. The scores may be modified as results are received and actions are taken. The advantage of this application of the inventive scoring system is that it enables efficient access to a universal means of identifying what needs to transpire or has transpired since the last updating and review of the primary note.
A preferred mechanism for display under “I” is to group according to score. Scores at or above a certain cutoff may generate an “alert” which could be in the form of an email, page, phone call, or special notation of an available display. This may be time-dependent, e.g., an alert would be generated 24 hours before the scheduled surgery. Depending on the score, it may provide options or mandates.
It is within the scope and spirit of this invention that an aspect of embodiments of present invention addresses the different requirements for acquiring information and addressing issues among healthcare providers. For example, the anesthesiologist would be more interested in obtaining and reviewing a previous anesthetic record; a surgeon might be more interested in tests to assess the spread of a malignancy. Hence, embodiments may contain subcategories with respect to Interim Information and Issues. A preferred way to populate these subcategories is via the user's code that is entered into a given cell (FIG. 17 ). Each healthcare provider could initially address his/her specific concerns, while still having the opportunity to review the summated issues. The following is one such listing; this can be adapted to the specific institution: A=anesthesiologist(s); S=surgeon(s); N=nurse(s); P=primary care provider; C=cardiologist O=other specialist/consultant; Σ=sum of all categories.
Within the electronic note, the “I” section gets repeatedly updated. The arrival of new information or the recording of new decisions may populate and co-populate the database in several ways:
-
- Update the item's “I” score
- Type-in or import the information as text in the “I” section. This enables healthcare providers to rapidly access “new” information obtained in the interim between original data entry and the present review. In the embodiments which have the aforementioned specialty designations within “I,” this information could co-populate the “I” section of the relevant notes.
- Co-populate and thereby update the “ASPIR” sections of database impacted by new information:
- Co-populate and thereby update features of the history and physical exam and resultant note. For example, if information from a cardiac stress test becomes available, then the “Ischemic Heart Disease” and/or “Stress Test” subsystems of the “CARDIAC” system would be updated with text, code and score (and a time stamp). Consistent with the inherent bidirectional nature of score-driven links, the updated text, code and score may then co-populate “I.” In order to facilitate review of the new information, the information remains under “I” until an authorized healthcare provider confirms its presence and accessibility in another portion of the database.
- Co-populate and thereby update other components of ASPIRIN™; e.g., Risk indicators
- Co-populate and thereby update integrated assessment scores and diagnostic and treatment algorithms.
- Generate new “alerts” or cancel existing one based on the newly received (and scored) information or the need for additional information.
- The aforementioned is designed for interaction by healthcare providers.
- While much of the co-population by new information is based on established pathways (and the text, code and score conversion index and dictionary to establish equivalency of terms), the subsequent review and integration of new information and confirmation of its scoring will be under the purview of the healthcare provider(s).
- When a healthcare provider reviews new information, makes a need decision, or carries out a needed action, this leads to changes in the “I” score and its implications on other aspects of the database. For example, Risk indicators (or less commonly review of systems) will be altered if an item in that section requires an action (e.g., altering a certain medication based on its score or its combined score in concert with another factor).
A preferred embodiment includes such a provision for information under “I,” with options to access details (FIG. 6)—e.g., via a drop-down menu. As an added safeguard, if critical information is pending from a given body system or Risk indicator and/or should be reviewed prior to surgery, then the SISS™ or SASRI™ can be annotated (as with asterisks or with the “I” score). These would automatically be modified in accordance with changes under “I.”
Special Needs (N)
Similarly, needed equipment, supplies and actions can be addressed under “N” eeds of the ASPIRIN™ display. Needs primarily will be generated by:
-
- selection of specific item from A of the ASPIRIN™ score (e.g., super-morbid obesity may require a large table)
- S of the ASPIRIN™ score (depending on the specific needs for the specific surgery [e.g., special table, need for equipment to rapidly transfuse blood])
- P and I of the ASPIRIN™ score (which may relate to the need for special airway equipment)
- Score driven features of the Risk indicators
- Score-driven items in Interim Information and Issues.
Listings under N can be score-driven in accordance with the options for displaying R and I. N may play a vital role in the mandated “time-out” prior to the onset of surgery. In addition to listing standard components, N could identify critical needs (display of which is score-driven) that should be included a final check (time-out) for the given patient. These could be based on components such as an “antibiotic score,” a score-driven determination of which patients require antibiotics on the morning of surgery
Non-perioperative Application of ASPIRIN™ or its Equivalent
ASPIRIN™ thus provides a unique array for consolidating critical information, not only in the perioperative period but in many other contexts, especially those that involve transfer of information about multiple patients. FIG. 6 i shows a sample array of an electronic data sheet and display that can be utilized on institutional computers, a hand-held PDA or for generation of printouts. Obviously, the full capacity of the system for provision of additional information and links as shown for the ASPIRIN™ display above is best achieved with electronic media. Nonetheless, even the printout would be a major advance for patient safety. The indications for this are summarized by some of the quotations in Table 1.
As for multiple components of the inventive system, most or all of the information to be included in this tool simply are generated seamlessly from clinical entries into the data base. In each of its settings, the ASPIRIN™ display can be configured so as to readily distinguish the different lettered categories. This automatically is done by the sequence in which they are placed (e.g., A, then S, then P . . . ). However, this may be supplemented with separators such as commas, differences in font, differences in color, or including the specific letter (e.g., A, S, . . . ).
Integration of ASPIRIN™ Components:
The goals of the present invention from a patient-care standpoint include facilitating the categorization, scoring and communication of large amounts of information, highlighting potentially high-risk situations, guiding perioperative planning, and providing a mechanism by which to analyze outcomes—with a mechanism that uses analogous coding and scoring for the spectrum of conditions and the gamut of sites for potential co-population. FIGS. 7A-C illustrate how the present body system may be applied to provide additional information on an operating room schedule. A given case could result in a ASPIRIN™ score ranging from “1,1,0,0” to “5systems, 5systems, 5,5,5items5item5item,” wherein score-driven superscripted body systems (body system-specific modified ASA and Surgical scores) and items (Risk indications, Interim Information and Issues, and Needs) are determined in relation to established cutoffs; i.e., communication and display of the alphanumeric presentation may be limited to scores of 3 or 4 so as to avoid listing relatively unimportant issues.
In addition to what in FIG. 3 are described as the “Inventive Array of Basic SHAPE™ Components” and the “Inventive Array of Modified ASPIRIN™ Components”, the present invention also introduces “SHAPE™ Inventive Derived Indices.” Many of these would not have been obtainable prior to the present disclosure of one or more inventive SHAPE™ components. Easy calculation, as well as further delineation, may be achieved through the application of a computer-based program for electronic and hard-coded data entry, automated scoring, storage, analysis, and export. This may include any component of SHAPE™ as well as imports from other compatible sources.
The data may be arrayed in columns for integrated assessment, e.g., the SMASH™ (SHAPE™ Multifaceted Assessment of Surgical Harm) indices described below.
Such integration of components enables one to more effectively delineate preoperative conditions, assess perioperative risk, and drive indications for the myriad potential applications (Table 2, FIGS. 3 , 5 and 24). The drive indications include: triaging for preoperative assessments by an anesthesiologist, primary care physician or consultant (and providing code-compatible justification for such); driving recommendations for laboratory tests; planning intraoperative personnel and resource allocation; implementation of special protocols (for example, for administration of beta-blockers); planning for postoperative intensive care; quality assurance; performance assessments; and investigations. (DIFF)
Managing Scores—Inventive Indices for Assessment of Resilience and Likelihood of Morbidity:
“The aforementioned factors contribute to the unique and robust quality of the SHAPE™ database and its inventive components for determination of inventive indices. As illustrated in FIG. 3 , the inventive integration and indices include:
1) an aggregate score of the patient's disorders that is based upon the body system-specific1-5 SISS™ scores (SAD™) described above. 2) What are referred to herein as SMASH™ (SHAPE™ Multifaceted Assessment of Surgical Harm) indices. The components are delineated by subscripts. Examples include:
-
- integration of physical status (ASA score) and Surgical risk and invasiveness (SOCU™ score)—this may be expressed as SMASHASA,SOCU. The comma indicates that the components simply are being listed. A specific mathematical function that is used may be delineated (i.e., replace comma with + to indicated summation). Alternatively, the function may be for multiplying or weighting as discussed above. As noted above, preliminary findings from my ongoing research indicate that the combined use of ASA PS and Surgical risk/invasiveness is a more accurate predictor of length of hospital stay (LOS) and hospital charges than either one alone. SMASH™ also may be modified or supplemented to identify and take into account special issues such as Risk Indicators by providing the letter code of the given issue, including the alphanumeric score, incorporating the alphanumeric score in the SMASH™ formula, or by adding, for example, 1 point to the score (for one or more risk indicators with a score above a predetermined cutoff).
- a SMASH™ index based on body system-specific scores which integrates the modified ASA physical status scores for body systems with disorders (e.g., scores ≧2) with the rating of surgical risk & invasiveness—this may be expressed as SMASHSAD×SOCU™. This may be accomplished by first adding the SISS™ scores for the different positive systems (to generate the SAD™ score) and then multiplying this by the SOCU™ score.
- a body system-specific SMASH™ index based on a body system-specific score of physical status and a body system-specific score (same body system) as to the effect of surgery—e.g., SMASHSIS×SICU™.
In the forms described above, the index is constructed so that a higher score indicates a greater degree of overall risk and/or perioperative complexity. Alternatively, an inverse function (or a low number on the described index) would indicate a lesser risk—what may be referred to a greater patient resilience in the context of the anticipated demands of the planned surgery.
As those skilled in the art will certainly appreciate, an alternative mathematical function may be selected. Potential variations also include converting patient status and surgical risk/invasiveness scores to points (as discussed above) and performing manipulations other than simple multiplication. Ultimately, the optimum score will be determined with outcome studies and aforementioned analysis.
3) Comparable indices of disorders for nonoperative settings. For example, SAD™ may be used as a mechanism to document illness in a manner comparable to that proposed for the perioperative settings. Likewise, assessments of resilience can be assessed and scored in the context of nonoperative challenges. As noted elsewhere, these may be based on the scores used in the perioperative setting or for “chronic” scores as well as for scores which evaluate local as opposed to systemic impact.
4) Airway Index that integrates scores assigned in Tables 11a and 11b. For the typical embodiments which score “Physical factors primarily affecting ventilation” and “Intubation predictors”, the index is termed the SHAPE™ Physical factor and Intubation Composite Evaluation (SPICE™). If the embodiment also includes a score based on reports of prior intubations, it may be termed the SHAPE™ Mask score, Intubation score, and Report score Composite (SMIRC™). These scores may be combined with the other SHAPE™ scores and indices described above (e.g., as a component of SMASH™) to generate new composite indices. Alternatively, scored information from a prior intubation may co-populate other portions of the database such as Risk Indicators and may prompt “Need” for special airway equipment.
5) Preliminary data suggest that a simple cutoff based on the SHAPE™ scores in the ASPIRIN™ display may be indicative of the need for increased concern, triaging, planning, testing and/or therapy (and to justify billing for such). As shown in FIG. 24 , SHAPE™ provides the inventive tools for an institution to establish cutoffs such as:
-
- the need to see an anesthesiologist prior to the day of surgery if the patient has:
- a score ≧4 in one or more categories (e.g., modified ASA, SOCU™, Intubation predictors, alphanumerics of Risk Indicators); or
- ≧3 in two or more categories.
- the need to see a cardiologist if the patient has:
- a sufficient cardiac-specific physical status score (e.g., ≧4 in the CARDischemia subsystem according to SISS™),
- a score ≧3 in multiple systems known to predispose to cardiovascular morbidity (e.g. CARDischcmia, CARDchf, CARDekg, CARDexercise, CNSischemia, ENDOdiabetes, RENALinsufficiency),
- or a score ≧3 in a single system (according to SISS™) prior to a surgical with a CARD system impact score ≧3 (according to SICU™).
- the need to take special pulmonary precautions if a patient has:
- a sufficiently pulmonary-specific physical status score (e.g., ≧4 in the CARDischemia subsystem according to SISS™),
- a score ≧3 in multiple systems known to predispose to pulmonary morbidity
- or a score ≧3 in a single system (according to SISS™) prior to a surgical with a RESP system impact score ≧3 (according to SICU™).
The determination of the specific cutoffs is addressed in more detail later in this disclosure and will be adjustable in accordance with future research findings.
Potential Arrays and Screens
- the need to see an anesthesiologist prior to the day of surgery if the patient has:
Embodiments such as that shown in FIG. 32 direct the user to features and subfeatures. Alternatively, one could start more proximally in a branch. Table 12 illustrates a section of one of several potential arrays for collection, storage and analysis of data in accordance with the spirit of the present invention; a methodology that demonstrates more advanced inventive features in the context of more elaborate branch-chain logic is described later (with reference to FIGS. 26-31 ). In this example and many others, S/sS/FC/F/sF pathways and codes and scores are not shown (since they likewise would be transparent to the user. As discussed below, Table 12 and other tables presented herein may be employed as screens of a graphical user interface when the present invention is employed in a computer based system. In accordance with the embodiment displayed in Table 12, negative (column 1) indicates that the given body system and its subsystem(s) essentially are within normal limits (no ASA scores of 2, 3, 4 or 5 in traditional 1-5 range). Positive (column 2) means that significant information has been entered into the given body system or subsystem(s). “Positive” may entail a wide range of responses, including any or all of the following effects or meanings:
-
- a) If positive is selected for a body system during real-time data entry (that is, by person performing the history and physical exam)—or if the body system is clicked on or otherwise identified in an alternative embodiment—then the body system has positive features and the program may highlight the subsystems, and their most distal branches (e.g. features) (e.g., the subsystems and features of the CARD system).
- b) If positive is selected for a subsystem during real-time data entry, then the program may jump to a screen with potential scored features of that subsystem (as illustrated in Table 13 where both a sample screen for (a) features of ENDO-subsystems Thyroid and (b) a sample screen for a drop down menu for features of Hyperthyroidism are shown) or enable access to a menu (for example, drop-down). In most embodiments, choices are associated with a default score (as seen in Table 13) as well as visible alternative choices and/or a menu to access alternative items and actions (Tables 4 and 5). The individual entering the data may then select hard-coded options, click negative or positive for hard-coded options, type in the available type-in fields, or update information that already has been entered or imported. As detailed below, one may expand upon one of the selected items by clicking on that item or selecting an option such as “type-in details”; or one can enter additional information (additional items, pertinent negatives) by first selecting the “type-in more features” option (or an equivalent).
- To ensure that the most critical features have been addressed, the program can mandate neg/pos selection for these features or it can specially designate them on the screen (for example, by placing them first, displaying them in larger font or identifying them with an asterisk), with agreement that those items within a subsystem or those subsystems of a system were addressed before a subsystem or system can be scored as negative. Hence, a subsequent caregiver can be assured as to what has been addressed.
- The display may be a list such as Table 14 or can be a modification of the display for the given body system as shown in
FIG. 32 . With varying column width to accommodate the length of given entries, theFIG. 32 display could serve as the basis for the actual report as one of several alternatives to a more traditional report. - c) If implementation of the present invention provides for a data source that is populated with positive information from another electronic source (for example, data that had been entered into another computer that has been copied or emailed to the given database, data that were scanned into the current computer), it may be identified in a variety of ways including as “positive” in
column 2 or by highlighting the given feature, subsystem or body system. One could view/edit data as deemed indicated. The data may have been generated by a variety of ways, including prior entry by another caregiver, the same caregiver, a patient (e.g., a questionnaire), or import from a testing facility. The source of the information can be recorded electronically, while tracking and display can be customized to user(s) preference. Depending on the degree of compatibility between the exporting and importing programs, the data may be imported as predetermined hard-coded features, as information that simply populates the appropriate system, or as information that more simply just appears in an open area of the database where it can be handled by the user. These aspects are detailed for a preferred embodiment described later (with reference toFIGS. 26-31 ) and may be facilitated by the text, code and score conversion dictionary (FIG. 10 ).

In accordance with a preferred embodiment detailed later in this disclosure, scoring can be generated at the feature and subfeature levels (as opposed to the subsystem, feature category, or descriptor level). Selection of (and/or electronic transfer of) hard-coded features and subfeatures generates a default score (in accordance with the SISS™ score introduced herein). For a hard-coded feature or subfeature, this is the score assigned to the given feature (based on user, institutional, societal, regulatory body and/or national guidelines). For a subsystem, it typically is the highest score assigned to any of the selected hard-coded features of the subsystem or entered by the user by accessing type-in more features and assigning a score to that entry. For a body system, it is the highest score assigned to a subsystem within that body system. As within subsystems, there is the option to type-in additional data within a body system—by selecting “other” for that body system, one can type in a new subsystem and features. Note, that although the single highest score likely will be selected for communication with subsequent caregivers, the component scores and cumulative feature score and subsystem scores also will be maintained in the data base.
As noted above, the caregiver performing data entry can enter a modified score by assigning a higher or lower value for a feature, body subsystem or system in the given patient. This enables a caregiver to make the determination in a given patient that, for example, five class 2 CARDischemia factors (for example, smoking, hypertension, long-standing NSST changes on EKG, noninsulin-dependent diabetes mellitus, high LDL lipids) may qualify for the CARD system to be rated as a 3. This option also may prove helpful if one wishes to record that a patient has improved as a result of therapy (for example, asthmatic improved after being placed on steroids). In such a case, one could adjust the score for the original hard-coded option (and use “type-in additional information”), select an updated hard-coded option, or use the option to type-in more features. Changes in scores can be tracked electronically and displayed if deemed advisable. A major advantage of the present invention is that SHAPE™ allows for clinical judgment while maintaining a database that retains a feature's base code (regardless of score) and tracks changes in scoring.
It will be understood by those skilled in the art that negative and positive are included in Table 12 for purposes of clarity. Simply clicking on the noted body system could be sufficient to highlight subsystems; the presence of a default (or modified) score would signify that the body system is positive.
As noted above, for most preferred embodiments scoring occurs at the feature and subfeature levels. By way of example, Table 13 shows how features such as those listed in FIG. 32 may relate to the selectable features for the ENDOCRINE system. Table 13a illustrates organization of features in terms of similarity of score; other means, such as similarity of features, are also achievable. Instead of checking neg or pos, in the illustrated embodiment, one would simply click on the positive feature. The default score is shown in parentheses; a change in score could be accomplished by a variety of potential mechanisms including changing the actual value or entering the score in a “Modified Score” column (or viewing a dropdown menu which lists the default score first) (Table 5). If one wishes to type-in additional information about a hard-coded feature, this may be accomplished with the “type-in add'l info” option (which may not be scored (descriptor), assigned a score by the user or assigned a default score based the scored item with which it is associated). Where there is a significant likelihood of the need for multiple details about a given feature or subfeature, hard-coded descriptors may be attainable by a variety of mechanism, including drop-down menus (Table 13b). The program can keep track of these typed-in entries so that they may eventually be incorporated into future versions of the program as hard-coded options. The coded and scored entry of type-ins is detailed with preferred embodiments described later (with reference to FIGS. 26-31 ).
An important aspect of the inventive system is the ability to record information that is deemed important in a preoperative note without concern as to whether listing all aspects of a problem will artificially increase its score. This is most effectively addressed in a preferred embodiment with unscored descriptors described later (with reference to FIGS. 26-31 ). The program can automatically prevent the cumulative scoring of overlapping features with item-specific override exclusions algorithm such that, for example, “current atrial fibrillation” and “current thyroid-related tachycardia” can both be listed but would not be additive. Duplicates are handled by the text, code and score conversion dictionary discussed above and illustrated in FIG. 10 . Options for managing multisystem disorders likewise was addressed above and is shown in Table 9. The embodiment illustrated in Table 13 is an example of how to establish a balance between desired detail and unwanted complexity.
The cumulative score for a body system is the total of all the scores for the subsystems within that body system. However, because of the likelihood for overlap among subsystems, unless indicated otherwise, the score for a body system is based on the highest score assigned to one or more of its subsystems. When the ability to cumulate scores is deemed preferable, the program may be modified to treat specific subsystems as separate body systems. For example, diabetes may be treated as being independent from the rest of the ENDOCRINE system.
The overall cumulative score for a patient is the total of the scores assigned to the individual body systems; i.e., the SAD™ score (bottom of Tables 12 and 14). However, in most embodiments, to maintain consistency with the standard ASA score for communicative purposes, only the highest scores would be used; e.g., the overall ASA score would be based on the highest system score (e.g., on the 1-5 or newly proposed 0-5 scale). The cumulative scores typically would not be displayed. Either way, they could be stored in a database for quality assurance, billing, and outcome studies and could contribute to the SAD™ score.
Table 14 illustrates storage of the information and scores in a database for three representative patients. For purposes of this presentation, all entries in this example are limited to system Endocrine—subsystem thyroid. However, the total database would include all body systems and other information deemed appropriate in accordance with the present invention. A more detailed database with coding is described later in this disclosure in reference to a preferred embodiment (with its accompanying FIG. 13 ).
Table 15 shows the logic used for a typical questionnaire, with the provision that the text (and codes and scores) be consistent with SHAPE™ if such matching is possible. Issues with respect to interfacing with questionnaires will be discussed with “Imports” later in this disclosure.

e.g., “Is your overactive thyroid (hyperthyroidism) well-controlled |
on medications?” |
If low, patient to respond to queries relevant to hypothyroidism and its |
treatment that match hard-coded SHAPE ™ shape options. |
It should be understood the preoperative version of the present invention described above is one of several potential embodiments, and could be modified with additional hard-codes and expanded type-in options for assessing, recording, communicating and investigating in other settings—including nonoperative procedures, intensive care and emergency settings and long-term care—without departing from the spirit of the present invention.
For longterm management, one may wish to record more detail about the history of a patient's disease and how it is impacting on daily living. An embodiment where such modifications for chronic (longterm) conditions related to thyroid disease are preceded by a superscripted “LT” sign is shown in Table 16.

Such programs could also provide alternative default scores when longterm as well as acute impact of a disorder is taken into account (described later in this document). Conversely, scores can remain consistent among longterm and acute-perioperative versions if one relies on other aspects of the SHAPE™ database (e.g., history of anesthesia-specific halothane hepatitis in Risk Indicators of the ASPIRIN™ display) to identify issues that have added impact in the perioperative setting. Either way, the actual challenges could be rated with the SICU™ score or an obvious modification thereof, wherein the lowest score (e.g., 0) would be commensurate with rest. The renaming for such purposes is simple: as described, SHAPE™ can be translated as Silverman-Holt Aggregate Patient Evaluation (as opposed to Preoperative).
Potential Applications and Advantages of the Inventive System
It is contemplated the present invention may be implemented in a variety of manners dictated by the technology available to the healthcare facility. Examples of the inventive features enabled by the inventive classification and scoring system(s) introduced herein fall under the classifications of:
-
- previously unavailable coding and scoring of information that is free-typed (not hard-coded);
- co-population, importing and exporting among multiple information sources, fields within the given program, databases, and diagnostic and treatment algorithms;
- development of a text, code and score conversion dictionary for these integrative functions;
- development of an Integrative Index for these accessing sections of the program (which may be a component of the conversion dictionary.
Some of these aspects will be discussed immediately below; others will be included in the following description of a preferred embodiment, with the realization that they are not limited to said embodiment.
Consistent with features cited above and more detailed descriptions below, the present invention is organized to be configured to enable hard-coded choices and type-in options for cross-population (with text, code and score) of different components of the database for a variety of purposes, including: entering information into relevant body systems, arrangement of information for the given preoperative note, storage in databases, identification of special needs, communication, quality assurance, and research. (These are addressed in greater detail in the discussions of co-population and exporting—and their facilitation by a conversion dictionary and interactive index discussed below). As such, SHAPE™ includes hard-coded options for specific issues that co-populate more than one program location (Some of the multiple options for text, coding and scoring in this context have been discussed above). This unique ability to cross-populate, simultaneously edit/update, and share a common coding and scoring system among different fields within the same database (for example, cigarette smoking in Habits and potentially Respiratory) and among different databases is one of the unique benefits of the present invention. The multiple cross-system components that can be populated in the manner within the SHAPE™ database include:
-
- a) Co-populating a body system such as Respiratory with a habit such as smoking.
- b) Potential perioperative risks (“R”isk Indicators in ASPIRIN™ display) with potentially undetected or poorly communicated problems, including: latex allergy; porphyria (with resultant sensitivity to barbiturates); hallucinations in response to narcotics and sedatives (not necessarily recorded as an allergy but nonetheless important to know); contraindications to medications (e.g., succinylcholine) which may be entered and hence listed in a variety of separate systems such as Renal, and Musculoskeletal and Central Nervous System; history of halothane hepatitis; and/or notation of medications or techniques refused by the patient. These not only will populate the relevant body systems and subsystems but also may intitiate special score-driven alerts (e.g., alert care givers of important “R”isk indicators or vital “I”nformation of ASPIRIN™). Consistent with the vital role of scoring to multiple aspects of this invention, decisions to co-populate the Risk Indicator section of the ASPIRIN™ display may be driven by the alphanumeric score. This reflection of perioperative risk may be greater than the body system-specific SISS™ score, hence, as stated above, the inventive universal database of body system-specific text, codes and scoring can be tailored to the perioperative setting. For example, the potential impact of gastro-esophageal reflux may differ markedly between daily life and the day of surgery. The impact of such co-population on cumulative scores such as SAD™ is addressed with respect to annotation with “=”, “+” and “+>” above and in Table 9.
- c) As indicated in the preceding paragraph, important “I”nformation pending also can populate or co-populate the ASPIRIN™ display and multiple database fields. Again, the consistent means of scoring may be applied (
FIGS. 17 , 18, 20-22) - d) Special Needs (“N” of ASPIRIN™) such as special perioperative monitoring, special anesthetic techniques, and/or the need for intensive postoperative care. Again, such listing may be driven by the condition's 1-5 score (or 0-5 score, etc). Such listing not only applies to management of medication but also devices; for example, reprogramming an automatic intracardiac defibrillator (AICD) before and after surgery. The present invention can be adapted to integrate the given patient's indications and contraindications for a given therapy. The information can be readily accessible in the cumulative database (or portion thereof) and can be displayed on operating room schedules and electronic records (including electronic anesthesia note and under “N” of ASPIRIN™ display). It likewise may be incorporated into a memo or note or transferred to a compatible computer in another office. It could lead to a prompt, which may be in the form of a letter or alphanumeric code for the given therapy or as a component of a more generalized symbol which indicates that additional therapy may be considered. As such, it enables preemptive planning and preparation, thereby reducing day-of-surgery delays and cancellations.
- e) Indications for discontinuing, withholding or initiating medications perioperatively. Using comparable mechanisms of entering, grading, integrating and exporting data, the present design may alert caregivers to the presence of medications that likely should be discontinued preoperatively (for example, clopidogrel (Plavix)) and/or indications for initiating a medication preoperatively (e.g., beta-blockers, discussed in detail below). Such an alert could be in the form of any of the following based upon user preference:
- a simple Risk indicator letter code;
- a graded letter code as in the aforementioned SHAPE™ Alphanumeric Score for Risk Indicators (SASRI™) (
FIG. 11 ); - co-population of the relevant subsystems (such as Plavix in HEME);
- creation of a system-equivalent labeled Periop Meds (probably not necessary);
- a preferred embodiment entails providing the score shown in
FIGS. 22 and 23 - f) Grouping or collectively exporting particular medical conditions that have a common impact despite being from different body systems. For example, what is termed by cardiologists as “plaque risk”—a compendium of cardiovascular conditions and risk factors (some of which may be subclinical) that might not otherwise be grouped together. More, specifically, the collective exporting of such data to generate cumulative scores to guide additional workups (for example, cardiac evaluation with stress test) or initiation of beta-blockers (independently or in accordance with guidelines recommended in the literature or institutional policy). The data may be derived from CARDIACischemia, CARDIACchf, CARDIACEKG VASCULARpvd, or ENDOCRINEdiabetes, RENALinsuff, CNSischemia subsystems or Multisystem ConditionsOBESITY, as well as Social History (e.g., smoking) and possibly other body systems or subsystems. Similarly, one may group factors that impact on a decision to employ specific forms of invasive monitoring where risks and benefits must be weighed (e.g., a pulmonary artery catheter).
- g) Grouping of data that otherwise would require chart-by-chart searching to determine the presence or absence of factors deemed essential to quality assessment and improvement programs such as the American College of Surgeons National Quality Improvement Program (ACS NSQIP). All of the data required for NSQIP can be co-populated via standard SHAPE™ data entry in the review of systems (as shown in
FIG. 32 ) or via the Risk indicators and alerts (as shown inFIG. 11 ). Co-population of NSQIP or rapid chart review each is facilitated by the inventive scoring system, wherein all positive NSQIP variables may be assigned a score ≧3. Such unique score-driven assignment facilitates co-population and also streamlines chart review; one only has to check for entries with a score of 3 or more. While incorporating NSQIP criteria into its scored hard-coded options, SHAPE™ maintains its ability to provide its consistent means of scoring. This also enables ready identification of the body systems with one or more positive NSQIP criteria since the given system would, by default, be assigned the score of its highest positive system. This also enables: - determination of equivalent terminology via the SHAPE™ text, code and score conversion dictionary;
- determination of comparable terminology via the SHAPE™ conversion dictionary that allows storage of comparable terminology for future assessment (and possible improvement of the NSQIP criteria) based upon system (or subsystem . . . ) and score.
- for NSQIP criteria and criteria complexes that do not correspond to scored features within a given bodily system, SASRI™ provides scored Risk indicators and alerts (
FIG. 11 ). As for the inclusion of Risk Indicators in the ASPIRIN™ display, the scoring facilitates categorization and determination of what qualifies for co-population of NSQIP. In the embodiment shown, the cutoff of ≧3 prompts co-population of NSQIP as well as inclusion in the ASPIRIN™ display.
The present invention also may improve the assessment of laboratory values within NSQIP wherein the lab values are recorded for approximately 13 indices. These can be scored in accordance with a graded scale such as that in FIGS. 17 , 20 and 21. Again, a score beyond a preset cutoff would determine which values correspond (via universal language and scoring) to abnormal NSQIP criteria.
It should be evident that the versatility of the present invention detailed in this disclosure is attributable, in large part, to the unique scoring and unique code/score language. This leads to score-driven co-population of notes, displays, alternative systems and databases, and algorithms. Unique options for managing codes and scores are summarized in Table 2. Aspects relevant to this portion of the disclosure include:
-
- recording (and modifying) the information within the database and the final note;
- recording the code, score and possibly text in the database directly into the ASPIRIN™ display or into a summary at the bottom of the note which can then be transferred to a display;
- co-populating diagnostic and treatment algorithms, indices and electronic or paper printouts with text, code and score.
With respect to the last option, it is further contemplated data for given body systems may be integrated to provide needed entries (typically at the feature or subfeature level) to co-populate with a common language and score established indices of risk assessment (that, while highly acclaimed, are not universally applied in their current form), diagnosis (e.g., whether to obtain a cardiology evaluation) and treatment (e.g., whether to initiate perioperative cardioprotection with beta-blocking drugs) algorithms. Exported entries may be generated from:
-
- their original field of entry (e.g., a specific feature within a given system); or
- a section of the SHAPE™ database that was co-populated by the original entry (e.g., co-population of the Cardiac System with the selection of
Type 1 diabetes in the Endocrine system; or - from Risk indicators (when appropriate); or
- a SHAPE™-derived index such as SMASH™.
It is described below and in Tables 17a and 17b (cumulatively referred to as Table 17) how, with relatively minor, transparent and easily understandable score translations, SHAPE™ could then convert different terminologies for different cardiac-related indices into a common language and more interchangeable scores and/or could activate the terms used in a given index with equivalent or relevant features. For example, the widely acclaimed Cardiac Risk Index of Lee et al. (Circulation 1999) lists six variables which primarily impact on the rate of major perioperative cardiac complications. According to that Cardiac Risk Index, the risk of an adverse perioperative cardiac outcome is directly related to the number of risk factors in the given patient. However, it is believed the classification and scoring described in the present invention overcome many of the limitations of the Cardiac Risk Index. For example, ischemic heart disease may be scored so as to enable distinctions not available from their similar “ischemic heart disease” factor; the simple variable “congestive heart failure” can be graded according to severity as well as to whether it is currently active and the grouping of a wide variety of surgeries as “major” can be improved with the SHAPE 1-5 SOCU™ classification and, more specifically, by the system-specific SICU™ classification. Such distinction may overcome the disparity between the odds ratios generated by the derivation and validation sets of the Cardiac Risk Index (Lee T H. Marcantonio E R. Mangione C M. Thomas E J. Polanczyk C A. Cook E F. Sugarbaker D J. Donaldson M C. Poss R. Ho K K. Ludwig L E. Pedan A. Goldman L.

Note |
The aforementioned system is in near total agreement with the detailed guidelines based the ACC/AHA guidelines (which lack the advantages of the inventive program as cited in the text). |
The Cardiac Risk Index excluded variables that have been considered vital to other indices for risk assessment and algorithms for diagnosis and treatment. This effect may be mitigated by a common database enabled by SHAPE™ such as the one in Table 17a which enables a common language and scoring system for the otherwise disparate indices and algorithms. No longer must health care decisions be based on an index that is isolated from other indices.
Looking at the currently available and the aforementioned SHAPE™ improvements, the six Cardiac Risk Indices variables are listed below along with quotes from relevant sections of FIG. 32 and Tables 10a and 10b that either are the given Risk Index variable or list a feature (with its score) which is suited to the given Risk Index variable. Note, the score provides additional information compared to the Cardiac Risk Index—precise features as well as score—while being programmed to maintain the simplicity of use.
-
- high-risk surgery: co-populate with entry in accordance with overall surgical risk/invasiveness (SOCU™) score of Table 10a; or more specifically, can co-populate with the score for the effect of surgery on the Cardiac system as a component of the SICU™ score (Table 10b).
- ischemic heart disease: co-populate with relevant features from “Ischemic Heart Disease” in
FIG. 32 and their scores (in parentheses), including: exertional angina (3); old MI (3); stable (3); old wall motion abnormalities (3); extensive wall motion abnormalities and ischemia on scan (4); unstable angina (4); angina at ≦2 METS (4) - congestive heart failure: co-populate with relevant features from “Congestive Heart Failure” in
FIG. 32 and their scores, including: compensated CHF (3), stable on current meds (3); history of pulmonary edema in past—presently stable on current Rx (3); symptomatic CHF with moderate limitations (3), EF 25-50% (3); severe CHF (4); severe pulmonary edema (4); cannot perform any physical activity (4); requires cardiac meds to function (4) life-threatening pulmonary & hepatic congestion (4) EF <25% (4).- The flexibility of the present invention is shown by the ability to co-populate different subsystems within the Cardiac System for joint exporting to the Cardiac Risk Index, while retaining the option to incorporate only one of the scored subsystems (e.g., Ischemic Heart Disease or Congestive Heart Failure) in the score for the Cardiac System for use in the SHAPE™ database and subsequent inclusion in the preanesthetic/presurgical note.
- history of cerebrovascular disease: co-populate with relevant features from “Cerebral Ischemia” in
FIG. 32 including: asymptomatic carotid narrowing (2), >80% carotid occlusion (3), history of transient ischemic attacks (3) or stroke (3); current TIAs (transient ischemic attack) (4), recent or acute stroke (4)- The flexibility of the present invention is further shown by the ability to co-populate different body systems (e.g., CNS and Cardiac) not only for joint exporting to the listing of six variables for the Cardiac Risk Index but also, as shown in Table 17 and discussed below, to a graded system such as the ACC/AHA Guidelines. With respect to the latter, the SHAPE™ database may export the relevant text with either: its CNS System score; with the score of its co-populated inclusion in the “Nonspecific Risk Factors & Indicators for Ischemic Heart Disease” Subsystem of the Cardiac System; or with a converted score designed for the transition from SHAPE™ to the ACC/AHA Guidelines. It should be understood that, although a history of stroke is rated as 3 for the CNS system, it is rated as 2 with respect to the Cardiac system since a review of the literature prompted the ACC/AHA Guidelines Committee to consider it to be a minor clinical risk factor for perioperative cardiac morbidity (Eagle: Circulation 2002). The SHAPE™-derived ability to use a common language with the scoring options described above enables concurrent assessment of multiple indices and algorithms. For example, the Cardiac Risk Index, the ACC/AHA guideline update on perioperative cardiovascular evaluation for noncardiac surgery, and a beta-blocker score all are available from the data tabulated in Table 17. These options for managing text and scores also apply to other items, including those with respect to Diabetes and Renal Insufficiency discussed below.
- insulin therapy for diabetes: co-populate with relevant statements from “Diabetes” in
FIG. 32 . - renal insufficiency: co-populate with relevant sections from
FIG. 32 , including preoperative serum creatinine>2.0 mg/dL (3): stable on dialysis (3), GFR<50 ml/min (3), advanced hepatorenal syndrome (4).”
Even simpler, SHAPE™ enables the potential to reduce the common language to scored “cardiac risk” equivalents based on CARDischemia, CNSischemia ENDOdiabetes, VASCpvd, RENALinsuff of SISS™ and CARD of SICU™. Examples of this include the designation of the following subsystems (as shown in FIG. 32 ) as independent of the parent body system for purposes of co-population of cardiac risk indices and diagnostic and treatment algorithms:
-
- the Congestive Heart Failure (CHF) subsystem in the CARDIAC system—this is one of the six factors in the revised Cardiac Risk Index and is an intermediate clinical risk factor in the ACC/AHA Guideline Update on Preoperative Cardiovascular Evaluation for Noncardiac Surgery. The flexibility of the SHAPE™ database is shown by its ability to accommodate such categorization and thus effectively generate a preoperative note and database entries, scores and displays (e.g., ASPIRIN™) while co-populating multiple diagnostic and treatment algorithms with a single language (text and/or code and/or scoring system). This may be accomplished in a variety of ways. A preferred embodiment entails generating the data for the CHF subsystem primarily from hard-coded choices in other subsystems of the CARDIAC system. The default option can then be to include the CHF subsystem in the final database and in exports for co-population of diagnostic and treatment algorithms but to not include this subsystem in the final note unless it is positive for items not included elsewhere. If a positive score in this subsystem is due to co-population from another subsystem, then the default option would be not to include CHF in a cumulative score. (As noted above, this may be designated by a notation such as “=”).
- the Cerebral Ischemia subsystem of CNS and the Renal Insufficiency subsystem of RENAL. These are important in and of themselves; identifying them as scored subsystems facilitates automatic exporting of the “common language” to diagnostic and scoring algorithms and related applications. These may simply be exported as “independent” subsystems to the indices and algorithms or they may be channeled to co-populate a portion of the Cardiac System such as a Nonspecific Risk Factors & Indicators for Ischemic Heart Disease Subsystem. Here, the code will reflect the feature's origin and its score may be modified if the cardiac-related impact is deemed less than the impact in its parent system.
- Exercise Tolerance. As per CHF, this typically is addressed in other subsystems of the CARDIAC system or in another body system RESPIRATORY). The default option may be to co-populate this subsystem with entries and scores from other program sections as well as to include exercise-specific items as may be generated by treadmill testing. The default option would be not to include Exercise Tolerance in a cumulative score since this does not in and of itself constitute a disorder. Of special note—the ACC/AHA Guidelines do not treat exercise tolerance as a minor, intermediate or major clinical risk factor. Instead, they rate it as a separate “good” or “poor” category which then augments or modulates the impact of the clinical risk factors. This is reflected in the inventive algorithm for converting the score assigned to exercise tolerance as a subsystem in
FIG. 32 to its role as a modifier in the ACC/AHA guidelines in Tables 17a and 17b. - The Diabetes subsystem, while appropriately included under the ENDOCRINE system for organization purposes, is programmed to co-populate the aforementioned diagnostic and treatment cardiac algorithms.
For the screens for given algorithms for consultation and/or treatment, several of the criteria for the given algorithms will be matched with identical statements in the components of the SHAPE™ score. Attempts are made to include exact wording within the review of symptoms. However, at times, more than one hard-coded choice in the review of body systems can be equivalent to or consistent with a single item in the given algorithm (or perhaps vice versa). In accordance with a preferred embodiment, they can all be included and identified with a common font, number code, or color. Additionally, they can be grouped together under a common heading via indentations or a drop-down menu. A preferred method is to assign them a subscripted code that includes the numeric subscript which identified the co-population pathway (as described later with respect to the screens for Diabetes in FIG. 30 ).
Also there will be situations in which a relevant item in the review of body systems does not match sufficiently with an item as stated in the given algorithm, but clearly identification of this feature is consistent with overall scoring and logic of the algorithm. In which case, they could be added during the co-population process with annotation to relate that they are distinct but similar, analogous to the annotations of “Similar Type-ins” described later in conjunction with a preferred embodiment as shown with reference to FIGS. 26-31 .
The integrated common language and scoring of the present invention may be referred to as SHAPE™ Cardiac Risk Assessment Points (SCRAP™). The points could be included in Risk indicators of the ASPIRIN™ display, or as an independent inventive index, or as a component of SMASH™. Decisions may be made based on the number of factors that are present, the presence of one or more factors exceeding a given cutoff and/or cumulative score.
In addition to enabling the aforementioned forms of customization for interfacing, the incorporation the text, code and score conversion dictionary (FIG. 11 ) enables development of a common language with a common score and a common terminology (and a mechanism for documentation terminology equivalency or similarity) that can be modified in accordance with its score for multiple sites of co-population. The inventive dictionary converts statements to a common language for co-population while also providing important details about the nature of the disorder and its severity. The unique combination of universal terminology and coding and scoring also may be applied to SHAPE™ interactions with scoring systems such as ICD-9 codes and CPT codes as discussed below in greater detail.
Thus, Table 17 uses such a common language and SCRAP™ to collectively cite the Cardiac Risk Indices of Lee and colleagues with the ACC/AHA guidelines for cardiac evaluation, as well as to generate a score for initiating cardioprotection with beta-blockers. The scores demonstrate how the SISS™ and SICU™ scores can be included in such algorithms. The values for the clinical risk factors are identical to those of the Cardiac system in the SHAPE™ database. The scores for surgery have been modified to expand the intermediate risk surgery from a single score of 3 to options for 2, 3, or 4 (as described earlier in this document). The difficulties that have hampered the inclusion of exercise tolerance in the ACC/AHA guidelines have been addressed by assigning a 1-5 ranking to exercise in the Exercise Tolerance Subsystem of the Cardiac System and then converting scores of 1 and 1.5 to −2 and a score of 2 to −1; scores >3 have no impact on SCRAP™. The different combinations are summarized in Table 17b.
Exercise tolerance is unique among cardiac signs and symptoms in that it is a form of a daily life test: whereas poor exercise tolerance (high score on SHAPE™ 1-5 or 0-5 scale) may confirm other signs and symptoms of cardiac disease, good exercise tolerance (low score) lessens the likelihood that the patient has significant cardiac disease. The adaptation of SHAPE™ to assign negative points to diagnostic and therapeutic guidelines not only enables more effective scoring of indications (as for determining the need for a cardiac evaluation) but also enables quantification of contraindications. Negative numbers can be assigned to specific items in specific algorithms; e.g., for a history of severe allergy to beta-blockers in the beta-blocker algorithm, for the presence of severe pulmonary hypertension in a scoring system designed to determine whether one should monitor with an invasive pulmonary artery catheter (which may cause pulmonary artery rupture in a patient with severe pulmonary hypertension). The degree of negativity can be graded, with a predetermined value indicating an absolute contraindication.
Advantages of the inventive mechanism of organizing, coding and scoring in this context include those related to the introduction of a universal language with scoring, as described above. In addition, the embodiment shown in Table 17 provides more information than the ACC/AHA Guidelines which does not account for uncertain exercise tolerance and does not take into account the number of risk factors or gradation of an individual factor's severity. Additionally, increased precision is provided by the 1-5 classification of surgery (especially with the system-specific SICU™ score). The use of a common language and standardized scoring systems enables smooth transition among applications such as the SHAPE™-modified ACC/AHA Guidelines and indications for beta-blocker therapy. One simply may select different variables for different application (e.g., one might argue that valvular heart disease should not influence the initiation of beta blockers for cardioprotection) or establish a different cutoff. Whereas a score of 6 or more in Table 17 suggests the need for cardiology evaluation, scores in the range of 5-7 actually may prompt one to forego the evaluation and simply initiate cardioprotection with a beta-blocker. Likewise, accumulation of a score of 6 or more solely as a result of minor clinical risk factors might prompt use of beta blockers as opposed to a costly evaluation. Such decisions would be prompted and facilitated by listing the factors responsible for a given score. At times, information from the cardiac evaluation may be used to determine beta-blocker use (while obviously not influencing the decision to perform an evaluation because it was generated by the evaluation). In such cases, the information (e.g., from an echocardiogram or stress test) may be entered as a new potential scored “risk factor” or as justification for modifying the score of an existing factor. Thus, clearly the inventive modifications (e.g., common language and scoring) provide greater information and flexibility than either the Cardiac Risk Index or the ACC/AHA guidelines alone (or even in concert). It is further contemplated exports from SHAPE™ may be used to co-populate other indices such as those that calculate Respiratory risk or likelihood of postoperative nausea and vomiting.
It should be evident that the unique classification with scoring introduced herein provides other opportunities for heretofore unappreciated co-population and export. This may be applied to such varied areas as ordering standard laboratory and specialty tests, triaging to anesthesiologists by nonanesthesiology caregivers, determining the need for medical or specialty consultation, transfer to a tertiary care facility, justification for increased billing (e.g., because of patient complexity), planning for required operating room time and postoperative intensive care, the performance of studies to determine benefit of certain forms of monitoring and therapy, and providing patients with coded cards or electronic storage which lists significant conditions (e.g., with scores ≧2 in any of the components of the ASPIRIN™ display). The latter has not been detailed prior to this section because it is dependent not only on the history and physical but also on the accompanying laboratory testing that may be prompted by the history and physical. It is, however, a vital component of the inventive program, whose unique properties are derived from the universal language, coding and scoring provided by SHAPE™. We will return to this aspect at the end of this disclosure, after the contributing components have been described.
With respect to laboratory testing, the SISS™ and SICU™ scores, or an integrated index such as SMASH™, can initiate jumps to suggested (default) testing batteries which may be modified as deemed appropriate. These can be coded (color, size, 1-5 class) in such a way so as to designate whether the test(s) is strongly indicated or simply should be considered. For example, for patients with thyroid disease a complete set of thyroid function tests likely would be indicated for a SISS™ 4 degree of dysfunction. However, they should be considered, but not necessarily obtained, for a class 2 score.
FIGS. 21A and 21Bb illustrate how driving (generating or suggesting) of testing may be accomplished. In particular, they a) show how epidemiologic factors and the surgical invasiveness score drive test and b) show how specific medical conditions identified in the score assigned in accordance with the present invention may contribute to the tests that are ordered. The integration of laboratory results is discussed with a preferred embodiment described below.
Especially when a modified ASA score of >3 is obtained for a given body system, options for optimization may be selected. This may include new therapies or generation of a consult request (FIG. 18 ). This can be done with a letter code, e.g., “con”, and then you could have cardiac or pulmonary. This would not only notify other healthcare providers that there is additional workup being done, but also that there is a chance for further optimization. The need for, and/or pending requests for, additional information can co-populate the “I” of ASPIRIN™.
It is further contemplated the present invention can provide medical practitioners with other important information that often is lost in the communication process; for example, that the patient refuses blood or has autodonated his/her blood for use during surgery. This option can be accessible at any time but may be prompted by the surgical score assigned to the patient (for example, if the SOCU™ score is 4 or 5 or, more specifically, if the SICU™ score for impact on the Hematologic System is 4 or 5.). Provisions for its appearance are provided by “R” and/or “N” of the ASPIRIN™ display.
With respect to the ASPIRIN™ display where a graphical user interface is displayed, if deemed preferable in a given setting (for space, HIPAA compliance, etc.), data may be available but not visible to avoid cluttering and/or to maintain confidentiality. Obviously, information can be stored in a computerized database. It also can be coded. Additionally, the presence of additional information can appear as an icon which generates a drop-down menu or jump by clicking on it or with a simple mouse over.
Of note, the EKG is the one pictoral component of the patient's record for which text and/or score often is insufficient. Textual descriptors do not relate nuances of the actual tracing or enable optimal comparisons of EKGs obtained at different dates and times. If the score for the EKG is 1 in the current 1-5 (or 0 in the proposed 0-5) system, then the report of the EKG generally is sufficient. However, a score of ≧2 may trigger inclusion of an EKG, if it is available electronically, in the note (If this option is available, it may be activated automatically by selecting a relevant feature in EKG subsystem, by choosing an include EKG option in the program; or access to the EKG may be obtained in the Information section of the ASPIRIN™ display (as shown in FIGS. 5 and 15 ).
Working Through the Beginning Screens of a Typical Embodiment:
A typical embodiment of the program and graphical user interface screens begins with industry-standard recording or importing of basic information about the patient (e.g., name, medical record #, date of exam, date of planned surgery, name of surgeon). Typically, the name of the surgical procedure is recorded at the time of surgical scheduling. Otherwise, it can be hand-entered at this time, preferably by selecting from a pick list. Ideally, the information that already is hard-coded will include not only the standard codes for the surgical procedure but also the inventive surgical risk/invasiveness score (1-5 or 0-5) and the inventive SICU™ score, wherein the anticipated impact on specific systems is delineated for scores where the impact is >2 (or another predetermined value). The healthcare provider performing the history and physical typically will include a description of the present illness at the beginning of his/her note. This can be designed to co-populate the affected body system and relevant Risk indicators. The screens will also provide the option to jump immediately to that system and work off its screens (and hard-coded choices).
The screens for Allergies, Medications, Social History/Habits, Prior Surgeries and Anesthetics will be similar to that of other body systems with the added provisions for co-population (e.g., of different sections of the SHAPE™ program and ASPIRIN™ display). Allergies ideally will be selected from a pick list. The selected allergy will be hard-coded to co-populate other screens such as the Risk indicator screen of the ASPIRIN™ display or to specific body systems in the review of body systems. For all other entries as well as type-ins, a user-generated jump will be available (e.g., right clicking, clicking a button which prompts such co-population, or selecting from a drop-down menu). Medicines will be handled similarly to allergy.
Social History/Habits (e.g., tobacco, alcohol, drugs) likewise will preferentially be selected from pick lists, with hard-coded choices for inventive co-population of relevant patient body systems (e.g., smoking may automatically be recorded as 1.5 in the RESPIRATORY system) and other aspects of the database. Prior surgeries will ideally be obtained from a pick list with options for type-in as in other parts of this program. Prior anesthetic experiences likewise will be obtainable from a pick list with options to type in as per above and options for co-population.
The review of body systems may begin with a screen which lists all possible body systems (including the aforementioned option to select a Multisystem disorder). One option is to select all the body systems that are positive so that the computer can subsequently enable all of those in sequence. However, since it is likely that the information will be recorded during the patient examination, it may be preferable to proceed through each body system sequentially as the history is being obtained. Thus, if one adhered to the sequence shown below, she/he would begin with the CENTRAL NERVOUS SYSTEM (CNS). If one clicks “negative” for CNS, then the computer will proceed to the next body system, PSYCH. If one clicks “positive” for the CNS system, then more specific choices will be enabled. Depending on the given embodiment, this may entail a variety of options for data entry, including:
-
- the choices for CNS in
FIG. 32 ; - CNS-specific choices on screens comparable to those shown for Endocrine in Tables 12 and 14;
- screens with progressive branching in accordance with the preferred embodiment described below with reference to
FIGS. 26-31 .
- the choices for CNS in
For each body system, the final note can be configured either to simply ignore all negatives or to display the negative subsystems as a group which is designated as being negative (e.g., “Negative for . . . ”). Those skilled in the art will certainly appreciate there are multiple alternative configurations that would be suitable for the aforementioned selection process; e.g., a drop-down menu with “No” as the default.
It should be noted that there are different options for graphically displaying the different body systems. For example, to consolidate, Eyes, Ears, Nose and Throat may be grouped together. However, in most embodiments each body system would have its own number. Additionally, certain subsystems may be listed separately. This is particularly valuable when one is citing factors for cardiovascular risk indices and cardiovascular diagnostic and treatment indices. In such cases, CNScerebrovsc ischemia, ENDOdiabetes, CARDischemia, and VASCpvd, may selectively co-populate the CARD system.
The inventive mechanism of coding and scoring systems according to a 1-5 scale may be accomplished in a variety of ways, each of which has its advantages and disadvantages:
-
- Simply having the user assign a score to each positive system as summarized below
- CNS (1 1.5 2 3 4 5)

- HEMATOLOGIC (1 1.5 2 3 4 5)
- FLUID & ELECTROLYTES (1 1.5 2 3 4 5)
- MULTI-SYSTEM (1 1.5 2 3 4 5)
- Base the system score on scored aspects of the system (automatic, electronic transfer, or type-in).
- Select hard-coded items grouped according to score on the screens for a given system (as shown in
FIG. 32 and Tables 12 and 14) - Select scored hard-coded items grouped according to relationship among items.
- Select scored hard-coded items on feature and subfeature screens according to the branched-chain logic of a preferred embodiment (discussed below and shown
FIG. 7 andFIGS. 26-31 ).
Embodiments with Coding and Scoring Based Upon Branched-Chain Logic:
- Select hard-coded items grouped according to score on the screens for a given system (as shown in
- Simply having the user assign a score to each positive system as summarized below
The next section of this disclosure will focus on a preferred mechanism for arranging hard-coded choices with branched-chain logic and for adding information from free typing or importing from other data sources. The section also addresses the use of the text, code and score conversion dictionary illustrated in FIG. 10 and the associated interactive index. The last aspects of the invention to be described will be: the integration SHAPE™ with other coding systems; and the integration of the information generated by the history and physical exam, imports from other sources and laboratory testing into a score-based patient information card (or comparable electronic storage) that records positive information based on the SHAPE™ score in a universal language with an established code.
This progression from body system to subsystem to subfeatures and descriptors is consistent with the general to specific questioning of patients. The unique advantages of SHAPE™ are generated largely by its mechanisms of scoring based on bidirectional branch-chain logic:
-
- If, based on the healthcare provider's assessment, a given body system is within normal limits, then the body system is assigned a score of I (in 1-5 scoring range or 0 in 0-5 range) and predesignated branches corresponding to known negatives are automatically assigned the same low score. This constitutes proximal to distal scoring.
- Conversely, if there are positive features or subfeatures within a body system, then it is scored “positive” and its subsystems are enabled. For each positive subsystem, the feature categories are enabled. For each positive feature category, the scored features, and possibly scored subfeatures and unscored descriptors, are enabled. With rare exceptions, scoring is at the level of relevant features and subfeatures, which then are consolidated into a single score for the parent feature category (based on highest score of a feature or subfeature), which in turn contributes to a score for the parent subsystem (default based on highest score of one of its feature categories), which in turn contributes to a score for parent system (default based on highest score of one of its subsystems), which in turn contributes to an overall ASA score for the patient (default based on highest score of one of its systems). This constitutes distal to proximal scoring. Descriptors relate information like right or left side or they enable a non-scored type-in to add information; it may help to explain a score but does not generate a score. This overall process uniquely enables optimal recording of all information for performance and recording the history and physical exam, an organized system for database maintenance, and a unique means of scoring that is compatible with the traditional use of the ASA physical status while communicating and storing a much greater degree of detail. Details of potentially overlapping features and subfeatures may be recorded, coded and scored regardless of whether they should be scored independently, since the score of the feature category is based solely on the highest score within a feature category. Likewise, for subsystems and systems. Hence, the SHAPE™ scoring algorithms can be transparent and noncumbersome to the user of such means of data acquisition. Additionally, the progressive branching of subsystems into feature categories and features is consistent with the branch logic commonly used for questionnaires and electronic records, where positive responses commonly generate more specific choices; this will be addressed in relation to importing (below).
- Specifically,
FIG. 9 shows:
- Specifically,
- one of the body systems (e.g., CNS),
- with two of its subsystems,
- each of which has two feature categories.
- These in turn have features, one of which has subfeatures, one of which has descriptors; another feature simply has descriptors.
- The score for each proximal portion will be the same as the feature score unless another limb of the branch has a positive feature with a higher score.
Text, code and score potentially can be entered collectively in a single field or in separate fields. However, although grouped or presented with the text for scored features and subfeatures in data acquisition screens, scores should be stored in independent fields for score-based assessments, analyses and integrative indices. The branching and coding may be flexible. If deemed necessary, additional levels, such as subsubfeatures may be added for a complex system such as Cardiac (although this has not found to be necessary).
A preferred obtain for coding is shown in Table 6. However, coding for features, subfeatures, and descriptors can be:
-
- Simply based on the given system; or
- Sequential within each level of branching; or
- Adapted to include established codes (e.g., ICD-9 codes for specific conditions as established by governmental and nongovernmental regulatory agencies) within the desired level of branching. For example, if a given feature is equivalent to that assigned a code of 22222 in another program (e.g. ICD-9 codes), the 22222 could be included at the appropriate level of branching—i.e., its inclusion at the subfeature level of branching may be further identified at 0.00022222.
Recording of the history and physical may be supplemented by: selecting a type-in option relevant to the hard-coded choice with its score (discussed later); and enabling an Import relevant to the hard-coded choice with its score (discussed later); and entering a less specific type-in or Import that is not associated with a hard-coded choice (as discussed below in greater detail)
The specific score relating to systemic significance (impact) of a given condition in a given body system typically stays with it within the given body system and, in preferred embodiments discussed previously, remains with it in a fixed FC/F/sF code. However, in other embodiments, alternative scores may be assigned for co-population of other body systems and other areas of co-population (databases, diagnostic and treatment algorithms such as that shown in Table 17a). Eventually, if deemed indicated, one could:
-
- assign weights to components of an integrated equation (such as that shown above for the equation predicting hospital costs);
- convert scores to points (as shown above); and
- convert scores to constants (as for Exercise Tolerance in Table 11a)
Unless modified by the user, the jump after a hard-coded choice is predetermined. This predetermined jump may take one of the following forms: remaining on the current screen so as to enable selection of another choice on the screen; jumping to the next more distal branch on the screen (e.g., from feature category to feature); and moving in parallel manner to another screen within a given branch. This would occur in the following settings: move from one descriptor screen to the next descriptor screen under the same feature or sub-feature; jump from one system to the next if one clicks negative for the system; or jump from one sub-system to the next if one clicks negative for the sub-system. These may be optional, or one may just simply skip negative systems, sub-systems, or feature categories.
Jumping to another system, subsystem, or feature category or to generic descriptors, as may be mediated by an interactive index and designated by arrows, letters and/or symbols.
Looking at the pathways for a potential embodiment in more detail:
-
- selection of a system is followed by a jump to a screen of its subsystems;
- selection of a subsystem is followed by a jump to a screen of its feature categories; and
- selection of a feature category is followed by jump to a screen of either its:
- Scored features—choices associated with inventive SHAPE™ Individual System Status (SISS™) scores. Selection a scored feature records the item as well as its score. It may keep the user on the same screen or may cause the program to next jump to: unscored descriptors; back to a more proximal portion of the branch chain (e.g., another feature category or a list of subsystems); to another body system which either is concurrently affected by the condition being described in the present system or is next in the logical sequence of the history and physical.
- Unscored features—choices that are not associated with a score (or only have a tentative score); instead, they provide information that is deemed important before the scoring screen is accessed. Selection of an unscored feature from this screen causes a jump to a list of scored subfeatures—as for scored features, each subfeature is associated with a SISS™ score. Selection of a scored subfeature records the item and its score. It then may keep the user on the same screen or may cause the program to next jump to: unscored descriptors; back to a more proximal portion of the chain (e.g., another feature, feature category or list of subsystems); another system (as per scored features above).
- selection of a descriptor records the descriptor. It may keep the user on the same screen or may cause the program to next jump to:
- another descriptor screen;
- back to a more proximal portion of the chain (e.g., another subfeature, feature, feature category or list of subsystems);
- to another system (as per scored features above)
Alternatively, the proximal to distal jumping within a given branch may be interrupted by a diversion designated by superscripted letters, symbols or arrows proximal to a screen header or one or more of its hard-coded choices. Examples of potential predetermined pathways include:
-
- means jump to a specific screen that is not distal to the present screen or next in the typical sequence of successive feature categories, subsystems or systems.
- means return to the screen that initiated a jump to a screen rather than to the next more distal screen or the screen next in the logical sequence of successive feature categories, subsystems or systems.
- means that there is another portion of the same system that also pertains to the given item. User could either: jump to that section at this time and then return to the present screen; or the user may elect to first complete the present screen and access the other screen(s) at a different portion of the program.
- means after jumping to next (more distal) screen in a sequence (e.g., from feature category to feature, of from scored feature to descriptor), the computer immediately returns to the original screen to enable additional choices on that screen.
- means after jumping to other screens (as indicated by letter codes) which are outside the proximal to distal branched logic, the computer jumps to the next distal screen in the present sequence.
- * means that if another specific system or Multisystem Condition is identified by selecting the given hard-coded option on this screen, then that system automatically is selected by the computer for positive identification in database(s) and note(s) and its options for data entry are enabled. Options for the user: proceed immediately to that system; proceed to that system upon completion of the given branch; accept as complete information that already has been entered into that system; or enter information into that system when it is reached during normal progression of the history and physical. (The relationships among a multisystem disorder and the systems it affects are described earlier.)
- a,b,c,d, . . . (English letters) take the user through a sequence of jumps through screens that generic for a given system; e.g., generic CNS descriptor screens as shown in association with the preferred embodiment described below.
- Alpha (α), beta (β). (Greek letters) indicate jumps to Generic Multisystem screens e.g., alpha (α) causes a jump to the Multisystem Condition screens devoted to Systemic/Remote Effects of Malignancies and Their Therapy.
If multiple jumping options exist after completing such a generic screen, then the user may select the next screen from the inventive Interactive Index (discussed later). In order to minimize any confusion with respect to scoring in the current preferred embodiment, no access to generic screens is programmed until after the Scored Feature or Scored Subfeature level.
Unless the letters are accompanied by or to indicate return to the present screen or a subsequent Descriptor screen, upon completion of the letter-designated screen(s), the computer will automatically jump to the next Feature Category or Subsystem with an alternative option to access the Interactive Index. The exception—if one selects “Other” from the present screen, then the default is for the computer to bypass the letter-coded superscripts (discussed below).
A subscripted numerical prefix may be used to document co-population of diagnostic and treatment algorithms that are based on information such as that designated by the given item (e.g., diabetes is a risk factor in Cardiac Risk Indices and a potential indication for perioperative beta-blocker administration).
It should be understood that these letters and symbols would not necessarily be visible to the user. However, they could be accessed by administrative personnel to document prescribed pathways and modify them as deemed indicated.
Before delineating major components of the embodiment of the inventive program shown in FIG. 9 and detailed in FIGS. 26-31 , relevant inventive components are addressed with respect to:
-
- entry of data—coded and scored type-ins; coded and scored imports; and
- organization and interfacing—the interactive index and the conversion dictionary.
Coded and Scored Type-ins:
Although a mechanism for free typing is available at all times (e.g., via a pen icon), the present invention is designed so the user preferentially selects hard-coded choices. Nonetheless, at times, one may wish to enter information that is different from the hard-coded choices. Without the present invention, this typically has meant that the information is simply recorded in an unspecified portion of a database or note, while sacrificing specificity of coding and the potential for selective scoring. The latter limitation was not appreciated to be a problem prior to the introduction of the inventive scoring herein. SHAPE™ has multiple type-in options which are designed to maximize specificity of coding and scoring while minimizing complexity for the user.
If the information is closely associated with a given hard-coded choice on a given screen, then user can select what I have called the “Similar Type-in” option that is available for each hard-coded choice and enter the information as prompted (e.g., if hard-coded choice said “evidence of heart attack six months ago” and user wanted to type “chest pain with troponin leak six months ago”). The Similar Type-in option may be accessed by one of several potential options, including a drop-down menu or right-click menu associated with this hard-coded choice. The advantages of this approach are that:
-
- it provides for entry of the type-in information into a relevant portion of the database;
- it provides appropriate specificity of coding, storage, linking and jumping; and
- if the hard-coded option is associated with a score, then this facilitates the assigning of and recording of the score for the type-in.
A preferred option for coding is for the Similar Type-in to have the same basic code as the hard-coded choice followed by a letter suffix such as the letter “a” (i.e., the basic code before the letter suffix would document the commonality with a hard-coded choice; the letter would designate that it is a type-in). The database would include the annotated code and associated text. The closeness of the match may be delineated by a second letter chosen by the healthcare provider (e.g. a=exact, b=equivalent, c=similar). Options for storing and communicating the hard-coded choice and type-in include:
-
- Type-in only for database and note
- Hard-coded and type-in for database and note.
- Hard-coded and type-in for database, but only hard-coded for note
- Hard-coded and type-in for database, but only type-in for note
- Hard-coded and type-in for note, but only hard-coded for database.
- Hard-coded and type-in for database, but only type-in for note
Even when there is not an associated hard-coded choice, the invention provides for specific coding and scoring:
-
- On screens where it is very likely that potential type-in information may not be closely associated with a hard-coded choice, selecting “Unspecified” will enable entry of the type-in on the given screen; the type-in then would be assigned codes that designate the branching proximal to and including the given screen. On feature or subfeature screens with scoring, “Unspecified” may be replaced with a “Scored Type-in” option. Here, the user is prompted to select a score for the free-type information. As for the “Unspecified” type-in option, the “Scored Type-in” option enables appropriate coding for a system, subsystem, feature category, etc. In addition, it allows scoring in the context of the scores assigned to other hard-coded choices on a given screen.
- On Descriptor screens, the selection of “Other” places the cursor at the beginning of a section (on the given screen or an alternative screen) for free-typing.
- A System Type-in screen at the end of each system serves as a safety net for recording, coding, and even scoring information pertaining to the given system. This screen should not be used when more specific options are available, since entry of type-in information onto this screen will provide less specific coding than entry within a specific Subsystem and Feature Category. Upon completion of the present screen, the default option is to proceed to the next system. However, the other jumping options are available. These System Type-ins may have a default code that is indicative of their nonspecific nature (e.g., 0.0000 . . . 99, 98, 97). This will facilitate storage, as well as future editing and moving.
- There also are provisions for a “Miscellaneous System” to enable recording of information that subsequently can be distributed to a specific system for coding and scoring.
- On screens where it is very likely that potential type-in information may not be closely associated with a hard-coded choice, selecting “Unspecified” will enable entry of the type-in on the given screen; the type-in then would be assigned codes that designate the branching proximal to and including the given screen. On feature or subfeature screens with scoring, “Unspecified” may be replaced with a “Scored Type-in” option. Here, the user is prompted to select a score for the free-type information. As for the “Unspecified” type-in option, the “Scored Type-in” option enables appropriate coding for a system, subsystem, feature category, etc. In addition, it allows scoring in the context of the scores assigned to other hard-coded choices on a given screen.
These inventive methods overcome the major problems with free text—as noted by Kazanjian (Kazanjian P E, Trempet K K, O'Reilly M, Khetetpal S: The electronic pre-anesthesia form: An integral component of a new anesthesia information management system, Seminars in Anesthesia, Perioperative Medicine And Pain 23(2):133-150, June 2004), “free text entries such as ‘low platelets’ could not be recognized and accounted for by the data processing engine.” The present invention ensures inclusion of a coded and, if indicated, scored entry in the database which can then be treated comparably to a hard-coded entry.
Many of the options for coded type-ins shown in the aforementioned preferred embodiment are applicable to less intricate approaches such as directed selection of features in FIG. 32 . Here, right clicking on a scored option can enable options for typing in free test associated with the coded item. Less specific but nonetheless scored entries can simply be entered into the appropriate scoring column of a given subsystem cited in the table (or in the overall system). Again, options may be elicited by right-clicking or its equivalent.
Imported Information: The program is designed to facilitate entry, coding and scoring of information imported from other electronic sources such as a computer, fax, or scanner (e.g., patient questionnaire, discharge summary, physician's note, other database). The inventive keys to this are entry at the appropriate branch level and establishment of compatibility with text, code and score conversion dictionary (FIG. 10 ). Imported information falls into several categories which may be handled in a variety of compatible ways, including:
-
- Information that is worded identically to hard-coded choices in SHAPE™, primarily as a result of deliberately matching the text and codes of the external source (e.g., questionnaire) with the SHAPE™ database. In such a case, the imported information may be batch transferred to the appropriate system, subsystem, feature category, feature, subfeature and/or descriptor. It is identified as an import by a means such as a letter suffix which may be specific for the given source. Ideally, the import will occur in bulk or in segments (based on word match, headings, question numbers or codes) but could be done on an item-item basis.
- Information that is similar to a given hard-coded choice but not worded identically can be directed to that hard-coded choice but would be annotated specially, as with double letters so to indicate the source (first letter) and that it is similar to (but not identical with) the SHAPE™ hard-coded item. When a common import meets the criteria of having items that are similar but not equal, then the conversion can be established so that bulk transfer may occur as for identically worded and coded sources. If deemed desirable, the code from the source (e.g., of the questionnaire) could be included in the SHAPE™ branched-logic code (i.e., as described below for inclusion of ICD-9 codes). Such interfacing may be mediated by the conversion dictionary, one of whose functions is the delineation of the relationship between different text fields.
- Information that is relevant to the History and Physical but not specific to a given hard-coded option may be imported at the appropriate branch level as a text field or its equivalent (i.e., like a type-in) and be coded according to that level with a special numeric code (e.g., 95,94,93, . . . 90) followed by a double letter suffix to designate that it is an import that is not associated with a coded hard-coded choice (or an alternative form of coding). Imported items could then be scored and/or moved to other portions of the SHAPE™ database so as to enable their use for SHAPE™'s multifaceted functions.
Matching between the import source and SHAPE™ may be based on a number of formats, including:
-
- word match
- codes
- numbering sequence of the questions
- subheading/section
The handling of imports in this manner provides a uniform way for entering them, coding them, and scoring them in the appropriate sections of the program. It also facilitates tracking them so the program may be updated to become more compatible with other means of data entry (e.g., electronic transfer, faxing, scanning). The number of steps required to ensure such entry will depend on the system compatibility.
Ideally, the names and coding of the information in the source of import (e.g., questionnaire) will be matched to SHAPE™. However, if this is not possible, the inventive system includes a conversion dictionary that defines the text, coding (and scoring) interface between SHAPE™ and each source of information. This enables matching to a hard-coded choice in the SHAPE™ program. As for free-typing, letters in a suffix may identify the entry as an import, identify its source, and define the degree of similarity to existing hard-coded entries. For example, if the SHAPE™ program contained a hard-coded option “recent CHF with pulmonary symptoms” that was assigned the code 0.0001 $3 and the source of the imported information had a statement “recent pulmonary edema”, then “recent pulmonary edema” would be entered into the program at the level of the aforementioned hard-coded option with a code akin to 0.0001A$3aa. The specific letter code suffix would be specific for the given source of input.
Organization and Interaction:
The conversion dictionary mentioned throughout is at the heart of interfaces with imports, as well for co-population with the SHAPE™ data and exports. Searching and display can be at the level of any or all of the following:
-
- Text
- Coding (with suffixes)
- Coding and scoring
The conversion dictionary could be expandable; if you have a new type-in or import and click yes, then it could be included in the conversion dictionary.
To simplify aforementioned selection and scoring hard-coded items as well as related type-ins and imports, selection of a hard-coded choice could generate a drop-down menu (or equivalent). Two examples follow:
-
- For an embodiment where selection of scored items is via drop-down menus, the menu for each hard-coded choice on a System, Subsystem, Feature Category or Unscored Feature Screen also may contain:
- No (default)
- Yes
- Similar Type-in which allows for free typing in a manner that enables modified coding (e.g., same basic code plus a letter suffix), storage, communication, linking and jumping in accordance with the hard-coded choice.
- Exact Import that is matched to an electronic input source (e.g., matched questionnaire)
- Similar Import that enables importing from another portion of SHAPE™ or another electronic source with modified coding (e.g., same basic code plus a letter suffix), storage, communication, linking and jumping in accordance with the hard-coded choice.
- a bidirectional jump to Conversion Dictionary to determine if there is relevant information from other sources or if there is co-population of other sections of the database with equivalent or similar entries.
- For an embodiment where selection is via drop-down menus, the menu for each scored hard-coded choice on a scored Feature or scored Subfeature screen may contain:
- No (default)
- Yes (1)
- Yes (1.5)
- Yes (2)
- Yes (3)
- Yes (4)
- Yes (5) (where sequence of numbers is arranged such that default score is listed first)
- Scored Type-in which allows for free typing in a manner that enables modified coding (e.g., same basic code plus a letter suffix), storage, communication, linking and jumping in accordance with the hard-coded choice. Moreover, since the hard-coded choice is scored on this screen, the “similar” text will receive the default score assigned to the hard-coded choice. As for the hard-coded choice, the menu (or linking) allows one to select an alternative score.
- Exact import (as above).
- Similar import (as above).
- For an embodiment where selection of scored items is via drop-down menus, the menu for each hard-coded choice on a System, Subsystem, Feature Category or Unscored Feature Screen also may contain:
The interaction of the different components of the SHAPE™ databases and related sites of import and export can be facilitated by an Interactive Index which may be integrated with the conversion dictionary. In its expanded state, this would include all the screens of the SHAPE™ database. Compressed states would facilitate navigation, which may be accomplished by text and/or code, with creep seek based upon successive typing of codes or text. Examples of the collective applications of importing and interfacing and utilization of the conversion dictionary and integrative index to achieve outcomes such as those cited in Table 2 include:
-
- Improved input from Questionnaires—Although the present questioning technique is consistent with established art for comparable questionnaires, other questionnaires do not quantify information in accordance with the present invention, do not enable entry of data as described herein (for example, with matched terminology), and do not provide options for data management illustrated in
FIG. 3 and/or described herein. For example, customization to achieve compatibility with the computerized acquisition, analysis, cumulation, display and communication program, most notably its characterization for a scoring system as present in accordance with the present invention. - Customized importing of EKGs and other “figures” wherein it is helpful for a care provider to be able to review a tracing, specifically when the 1-5 score indicates a predetermined level of pathology The need to include the actual tracing may be driven by score assigned to the findings in the appropriate subsystem(s) of the Cardiac System (as shown in
FIG. 32 ). This will drive decisions as to where to display EKG (e.g., ASPIRIN™ Display; a compressed “SHAPE™ wallet” card described below). - Integrated development of diagnostic, treatment and communication scripts based upon the cumulated positive findings (e.g., above a certain score) in the varied aspects of the database, including the history and physical, SICU™ rating of surgical risk/invasiveness, scores assigned to laboratory results (discussed in subsequent description of a preferred embodiment). These may focus on specific medical conditions and/or specific surgical procedures.
- Identifying items that are germane to specific risk indices such as the factors that should be considered in a patient with documented or suspected ischemic heart disease.
- Interfaces concerning such issues as information, policies, guidelines and alternatives institutional material on the given computer or internet: for example, pharmacy, labs, policy manuals, other offices, educational material:
- PDA's which can interface with the main program to enable partial or complete transfer of patient data or other information;
- electronic texts and related materials; of note, the inventor has edited one review book in anesthesia and is editing a mini-text (with accompanying PDA version) wherein the code assigned in accordance with the present invention terminology and text terminology can coincide for rapid jumping and transfer (—vital information could be directed to desired part of database);
- other resource material on Internet;
- risk indices and related material (stored on computer or via web) to enable the score assigned in accordance with the present invention to be immediately compatible with the terms used in that index and thereby enable automated calculation of the given index; for example, there could be terms and fields for the established Cardiac Risk Index and for the American College of Cardiology/American Heart Association guidelines for preoperative cardiac evaluation; and
- likewise could jump to site that gives precise recommendations for SBE (subacute bacterial endocarditis) or DVT (deep vein thrombosis) prophylaxis that could be down-loaded to portion(s) with the relevant code assigned in accordance with the present invention with corresponding terminology.
- Improved input from Questionnaires—Although the present questioning technique is consistent with established art for comparable questionnaires, other questionnaires do not quantify information in accordance with the present invention, do not enable entry of data as described herein (for example, with matched terminology), and do not provide options for data management illustrated in
After the list of body systems, the next screen would be a list of the different subsystems of the CNS system. The user either could highlight all positive subsystems or proceed through the positive subsystems sequentially. Either way, selection would enable (activate) screens more distal in the body system. If a subsystem is negative, it simply may be skipped.
If one selected the Seizures subsystem, then this would initiate a jump to a screen of feature categories for the Seizure subsystem (FIG. 26.1 ). The pathway and its standardized punctuation (System: Subsystem: Feature Category/Features//Subfeatures—Descriptors) have been included in many of the headings for purposes of clarity in this demonstration. These details could be available for training sessions but would not be needed for day-to-day use by an experienced user. The user would select the feature category that is most appropriate or otherwise type in an alternative. This would cause a jump to the feature screen for the given feature category. The first such screen is shown here as a series of scored features under the heading Control of Generalized Tonic-Clonic Seizures (FIG. 26.2 ). The numbers in parentheses represent the default score for the given feature. The “Scored Type-in” option is explained briefly in italics and was described in the discussion of Type-ins above. The subsequent screens illustrate what would happen if one had selected Generalized Absence Seizures (FIG. 26.3 ), Complex Partial Seizures (FIG. 26.4 ), or Simple Partial Seizures (FIG. 26.5 ).
After the user selects a scored feature on the “CNS:Seizures (subsys):Generalized Tonic-Clonic Seizures (feat categ)/Control (scored features)” screen, the subsequent jump is to the first of four seizure-specific Descriptor screens (FIGS. 26.6-26.9). On each screen, the user would select the relevant hard-coded unscored descriptor(s).
-
- Some of these are preceded by a “” which indicates that the item also is addressed on other screens within the same system (e.g., a subsystem or feature category that has additional information about this item). User could jump to that section at this time but probably best simply to access it when you come to it in the program.
- The English letters preceding the fourth of these Descriptor screens indicate that, unless otherwise directed, the computer will jump to a series of generic screens (which are shown in FIGS. 27.1-27.7).
- The first letter-coded Generic CNS screen is “a” (=Brain Region Descriptors). This allows one to select one or more of the hard-coded choices or to type in additional information about the location of the seizure focus. As stated above, these descriptors describe the nature of the seizures but are not in and of themselves associated with a specific score.
- “n/a” (not applicable) or its equivalent allows one to quickly jump to the next screen. The need for this may be avoided on a given screen when a “skip” is built into selected choices on a preceding screen.
- The computer next jumps to “b” (=Generic CNS Descriptor Screen for Global CNS Signs and Symptoms (s/s)).
- After “b” the computer will jump to screens “e” (Sites of Peripheral s/s), “f” (CNS Tests) and then to screen “g” (CNS Treatments). Notice on the CNS Treatments screen that the hard-coded choices for Radiation and Chemotherapy are preceded by an * to enable entering information about Multisystem involvement (as per the bottom of
FIG. 32 ). - Other items are preceded by an asterisk (“*”) which indicates interaction with another system (in accordance with list shown on
FIG. 28.1 ). If one jumps to the screens of that system at this time (via menu option or via Interactive Index), then the computer will automatically return to the screen from which the bidirectional jump originated (or the user can access the Interactive Index after entry into the new screen(s) is completed.
If one selects the Cerebral Ischemia subsystem, then the screen would jump to the feature categories that are shown. Selection of a given feature category jumps to a screen with the features for that category. As opposed to the Seizures subsystem, where scoring was at the feature level, in the present subsystem unscored features have been included for each feature category. Selection of an unscored feature enables a scored subfeature screen and causes a jump to that screen. Consistent with the aims of the present embodiment, jumps to descriptors are configured so that they occur after the scoring so as to ensure consistency and inclusion of desired details in the final note and database without concern about affecting scoring by the degree of description that is provided. (While helpful, this is not a requirement for other applications of SHAPE™). As for other screens, the jumps to genetic screens (FIGS. 27.1 , 27.6 and 27.7) occur after the selection of a hard-coded choice. Although not shown here, the generic screen may be customized so the most relevant choices for a given jump to that screen may be highlighted (or similarly designated).
The first feature category of “CNS: Cerebral Ischemia” (FIG. 26.10 ) is “Asymptomatic Carotid Disease”. If this is selected, a series of unscored features is provided (FIG. 26.11 ). Selection of a hard-coded choice on this screen causes a jump to a subfeatures screen (FIGS. 26.12 , 26.13 or 26.14) which illustrates two unique aspects of the program noted above: scored subfeatures (after unscored features or features with a tentative score, as opposed to more established default score); and letters in the prefix designating the jumping pathway after choice selection on the given screen. Each scored subfeature is associated with a default score, which may be changed by the user. This screen also provides an option for Type-in with a prompt for the user to select a score. This obviates a major shortcoming of other data acquisition programs—where Type-ins typically are not coded or scored. As noted above, free-typing would be associated with a hard-coded choice and the type-in option would be accessed via that choice so as to optimize coding and scoring.
Selection of TIA (trans ischemic attack) or stroke initiates similar jumps to an unscored features screen (FIG. 26.15 ) which delineates timing and then to a scored subfeatures screen (TIA on FIGS. 26.16-26.18; stroke on FIGS. 26.19-26.22). Notice that the heading for each subfeature screen in this part of the program is preceded by a series of English letters which take one sequentially through the screens for generic CNS descriptors a-g (FIGS. 27.1-27.7). The sequence of Generic CNS Descriptors for TIA or Stroke bypasses the screens specific to seizures; instead, it includes screens that detail neurological signs and symptoms.
There is also an option on the “Cerebral Ischemia: Feature Categories” screen for typing information about other forms of cerebral ischemia if they should occur by selecting “Unspecified Cerebral Ischemia” or “Other” as described below.
If one selected the subsystem for Nonischemic Cerebrovascular Disorders (FIG. 26.23 ), then he or she would see the list of feature categories beginning with AVMs and Aneurysms. Each feature selection causes a jump to a subsequent screen of unscored features (FIGS. 26.24-26.32). Although these features may very well influence the score and thus are taken into account, the score is not officially assigned until the program jumps to one of the subfeature screens based on the hard-coded feature options. As before, most of the scored subfeatures are associated with a default score but there are other options. After the subfeature is selected, the computer jumps to the lettered generic CNS screens (a-g in FIGS. 27.1-27.7) delineated in the screen header. Exception—if “Other” is selected on the Nonischemic Cerebrovascular Disorders screen, the computer will jump to the type-in screen for typing and scoring at the end of the screens for the given system.
The last feature category for the Nonischemic Cerebrovascular Disorders subsystem is the Headaches feature category. If one selects this feature category, then one jumps to an unscored feature screen for Type of Headache. Depending on which feature is selected from this screen, one jumps to the scored subfeatures of mild, moderate, severe, or life-threatening (FIGS. 26.33-26.36).
If one selects the CNS subsystem of Nonmalignant Intracranial Mass, then s/he would jump to the feature category screen which lists different nonmalignant masses (FIG. 26.37 ). The subsequent unscored feature screen lists potential tumor locations (FIG. 26.38 ). The subfeature screen contains scored hard-coded choices (FIG. 26.39 ). This screen is followed by two descriptor screens (FIGS. 26.40-26.41; the “Yes” selection on the second screen is preceded by English letters delineating jumps to generic CNS screens (FIGS. 27.2-27.7).
If one selected the CNS subsystem for Malignant Intracranial Mass, then s/he too would go to a screen of different types (feature categories) (FIG. 26.42 ) and then to the unscored feature screen listing different potential locations (FIG. 26.43 ). Scoring again is at the subfeatures screen (FIG. 26.44 ). This is followed by several descriptor screens (FIGS. 26.45-26.47). The “Yes” option of the “Effects of Malignant Tumor or Therapy Within CNS” descriptor screen (FIG. 26.46 ) is preceded by letters delineating jumps through the generic CNS descriptors (FIGS. 27.2-27.7). Upon completion of the letter-coded jumps through the generic CNS descriptors, the computer will proceed to the next descriptor screen within the Malignant Intracranial Tumor subsystem.
On the next descriptor screen, with the header “Systemic or Remote Effects of Tumor or Therapy (FIG. 26.47 ), the “Yes” is preceded by the Greek letter “alpha” (α) which indicate a jumps to the Multisystem screens related to systemic/remote effects of malignancies and their treatment (as shown at the bottom of FIG. 32 and detailed in FIG. 28.2 in its series of multisystem conditions). The ensuing screens describe effects of the malignancy and its it treatment (FIGS. 28.3-28.6). Depending on the selection, one will jump to screens with additional descriptors that include lists of chemotherapeutic agents and their remote/systemic effects (FIGS. 28.7 and 28.8). The next screen illustrates what would happen if one selected radiation, either alone or in conjunction with chemotherapy. It prompts the user to include whatever information might be relevant and available (optional) and then jumps to the relevant side effect screen where one is prompted to either say that there were no side effects or to list them and their impact.
Note the special form of scoring for this Multisystem condition in the embodiment. On these Malignancy screens, there are no specific scored features; such specified scoring is reserved for individual systems. Instead, there is a prompt for the user to supply an overall score for the features of the systemic effects of chemotherapy feature category (FIGS. 28.6 , 28.10 and 28.11). As stated earlier in this document, s/he is then prompted to state whether this score should be labeled with an “=,” “+,” or “+>” (Table 6). Note, also that since the score that is assigned is not necessarily for a specific feature or subfeature, the descriptors are not restricted to the most distal point of branching.
The next screen dealing specifically with the Central Nervous System concerns Intracranial Trauma and Injury (FIG. 26.48 ). After selecting a feature category which will be listed in the note, the user jumps to a common feature screen for all of the listed feature categories (FIG. 26.49 ). Scoring occurs at the subfeature level (FIG. 26.50 ).
The next series of screens handles CNS infection in a similar manner (FIGS. 26.51-26.53). Some (a partial representation) of the potential infections that may be included on this list are included as feature categories. For each of the specific infections, the user jumps to a common feature screen that has the signs and symptoms along with their scores.
The next series of screens deals with ICP (intracranial pressure) (FIG. 26.54-26.56). Again, the feature category screen lists potential causes (see FIG. 26.54 ). Then there is a common screen which lists and scores the signs and symptoms (see FIG. 26.55 ). Of note, provisions for an item such as ICP are unique in that it is also listed as a sign/symptom in the generic CNS screen for global CNS signs and symptoms (FIG. 27.2 ). Because it is listed as a separate sub-system, its inclusion in the generic CNS screen for global CNS signs and symptoms is preceded by a double-sided arrow. This arrow would prompt a jump to the ICP signs and symptoms feature screen so as to ensure that the details of increased intracranial pressure are addressed at this time or at another portion of the program (discussed above).
The next screens deal with altered cognition (FIG. 26.57-26.58). As per increased ICP, this also is listed as a general CNS descriptor for other conditions (FIG. 27.2 ).
The final two screens of FIG. 26 deal with the sub-system of Parkinsonism and other CNS-based movement disorders (FIG. 26.59-26.60). The feature category screen lists two of the many potential disorders that can be listed on this screen. The next screen shows the features of the specific disorder; their severity is rated on this screen. The letters preceding the header indicate that there are jumps to other CNS screens to enable selection of unscored descriptors.
At the end of each system, there is the option to type-in and score “Other.” The score for the system (and its scored components) may be displayed. If a score has not been determined or if the user wishes to modify the assigned score, s/he is prompted to do so before moving on to the next system.
Then, on to the next system or subsystem: PSYCHIATRIC DISORDERS and PAIN (FIGS. 29.1-29.7). Of note on these screens is the design which enables documentation of the use and effect of therapy and its influence on the score. This provides two important pieces of information—current signs and symptoms and what they would be in the absence of therapy.
The header on FIG. 30.1 indicates Endocrine System:Diabetes Mellitus subsystem/Feature Categories. The next two screens are at the scored feature level—depending on the choice that is selected, the computer will jump to either the screen with the scored features concerning control of Type 1 (FIG. 30.1 ) or Type 2 diabetes (FIG. 30.2 ). Depending on the hard-coded choices, there are then several potential jumps to descriptor screens which include:
-
- insulin requirements (
FIG. 30.4 ); - glucose management (wherein the user is prompted to type in important data that is important to the note and database) (but will not have any new impact on scoring) (
FIG. 30.5 ); - Glucose values (
FIG. 30.6 ) with an optional table is provided to enter such data about descriptors (FIG. 30.7 ); - HbA1C levels as an indication of diabetic complications and sequelae with options of n/a (not applicable), none, or any one of the various bodily systems (
FIG. 30.8 ); and - Interactions with other systems are designated by an *, with potential jumps to systems that may affect or be affected by diabetes (
FIG. 28.1 ).
- insulin requirements (
For purposes of simplicity, selections that may be available on a given screen may actually be an integration of 2 or more features or a feature and a subfeature. For example, it may state “severe hypertensive nephropathy”. This would tell you that there is a severe nephropathy (feature) and there is a hypertensive nephropathy (also a feature). By way of another example, it may state “Pronounced hypoxia requiring continuous oxygen”. This is actually a feature and a subfeature combined, wherein pronounced hypoxia could either be a 3 or 4, but the requirement for continuous nasal oxygen would be a 4. If feature category would be 4, and a given item itself together is 4 to 4. However, in the database, it would be listed as 2 separate entries: pronounced hypoxia requiring continuous O2. For this particular patient, the pronounced hypoxia would be scored a 4 in the database, because it provides that number from subsequent subfeatures. Regardless of its score, its total would be that of pronounced hypoxia. The flexibility of SHAPE™ for co-populating different body systems, displays and notes and for exporting to diagnostic and treatment algorithms as well as different databases and programs is vital with respect to a disorder such as diabetes. Applications include:
-
- Co-population of other body systems affected by this disorder. Even if a diabetic patient does not have evidence of diabetic-induced cardiovascular disease, the presence of this risk factor could be documented with a CARDIAC score of 2 (consistent with its inclusion as a Minor Cardiovascular Risk Factor in Table 17).
- Co-population of algorithms that weigh cardiovascular risk factors and treatment regimens (e.g., the perioperative administration of beta-blockers in patients at risk for a myocardial infarction as delineated by subscripts 1-3 in the Diabetes screens). Scored as well as unscored data may be transferred automatically; the prescribed paths may be designated, as by a numerical subscript before the hard-coded choice.
- Co-population of the ASPIRIN™ display, such as to designate need for therapy on the day of surgery (e.g., subscript “4” on the Descriptors Describing Plans for Therapy of Diabetes screen (
FIG. 30.11 )
The universal application of the present invention thus has been demonstrated with respect to attaining, storing and co-populating (with exporting) the information attained during the history and physical exam. The present disclosure will next illustrate how information from two forms of testing—routine laboratory testing (with accepted ranges of normality) and EKGs (wherein clear cut criteria may not exist) may be included.
Laboratory tests could be recorded as per routine in the institution laboratory database but also co-populate sections of SHAPE™ where they can be recorded, coded and scored for storage in a Laboratory (LAB) “system” (or as a subsystem in FLUID & LYTES) as well as with specific body systems (e.g., liver function tests with liver), and/or Risk Indicators, Interim Information and Issues and where they can be used for analysis, display and distribution to interfaced notes, algorithms etc. Again, the 1-5 (or 0-5) system is used in a series of screens as illustrated for the lab values for potassium (FIGS. 31.1-31.5).
Inventive formulas convert lab values to scores. One such method is shown in FIG. 17 . Alternatively, one could establish other criteria. For example, if normal range for potassium is 3.5-4.5 mEq/l, then 3.3-3.6 may be scored as “borderline low-normal” which is scored 1.5 in the current example; 2.7-3.2 as slightly below normal (score of 2); 2.0-2.6 as significantly below normal (score of 3). Abnormal values that generate the specified cutoff can trigger score-driven jumps to screens which list medications that commonly cause or are affected by the given abnormality (e.g., low potassium can lead to digitalis toxicity, diuretics can lead to low sodium). Likewise, the abnormal values can be linked to relevant medical conditions and to surgery which may exacerbate the disorder (e.g., transurethral resection of the prostate with bladder irrigation would be identified by the SICU™ score as affecting electrolytes (exacerbating hyponatremia).
Links will influence level of concern and decisions with respect to treatment of abnormal chemistries. For example, if patient is taking digitalis, this would not only be listed in medication screen but also co-populate CARDIAC system with the option for a separate screen that records Factors Affected by Electrolytes. This would be co-populated with relevant entries from Medications, Fluid and Electrolytes, Kidney, GI as well as sections from the SICU™ score for the upcoming surgery. Hence, the present invention has scoring options for a number of the hard-coded choices.
An institution would have the option of tailoring the program so that Lab Results is a subsystem of FLUID & LYTES. The problem with this is that lab results often do not become available until after the History and Physical are obtained. Thus, such a wide range of “late arriving” information that can be relevant to multiple systems might best be handled separately. Conversely, system-specific tests preferably should be included in the associated body system—e.g., cardiac stress test in CARDIAC or pulmonary function tests in RESPIRATORY.
In certain situations, the textual description associated with a score may not be sufficient to effectively relate the abnormality. Although criteria for scoring an EKG have been provided in FIG. 32 , in the acute perioperative setting it is difficult to include sufficient hard-coded criteria to effectively describe potential EKG abnormalities. Hence, if an EKG is sufficiently abnormal, the coding and scoring of the present invention can prompt access to the actual tracing (FIG. 10 by special notation in the ASPIRIN™ display (and relevant sites of co-population) if an electronic version is available (as shown in FIG. 3 ). Otherwise, it may prompt the inclusion of a printed copy with the preoperative note.
In addition, the concise database of text, code and score can be applied to provide patients and their caregivers with compact information about an individual's health status. Data can be stored in common language or code, preferably according the logical branched-chain code described below and with respect to FIGS. 26-31 . Selection of information for such storage will depend on the scores of the coded features. For example, it may be limited to conditions which merit a predetermined score (e.g. ≧3) in any of the many components such as SISS™, SMASH™ or the ASPIRIN™ display. If listing is only in code, then the code will relate the system, subsystem, feature category and feature as per FIG. 7 , with desired provisions for HIPAA-compliant (i.e., privacy protected) access to all components or selected components with coding. Even without an extensive dictionary, one may readily access a key which relates the codes of individual systems; identification of the systems affected may require little memorization than that required to memorize the names and sequence of the nine planets. Additionally, scores beyond an established cutoff (e.g., ≧2) may drive optional storage of additional information beyond that of coded text (typically of test results), including:
-
- Actual laboratory results
- A copy of the patient's EKG since, as noted above, the tracing often is worth a 1000 words. However, while the coding described above allows for consolidated presentation of coded conditions with a sufficient score, printout of an EKG typically is on 8×11 inch paper. Therefore, in order to meet the space confines enabled by score-driven selection of data for card storage, the EKG will be consolidated with inventive processes. In a trial among colleagues at Yale-New Haven Hospital, I confirmed that the configuration shown in
FIG. 10 is the smallest that enables visual interpretation of the abnormalities typically responsible for a score ≧2. It may be stored as a second wallet-sized card (fits in a holder) or on the back of main information card (described above). Such an EKG may be derived by digital reduction of a commercially available option to configure parallel columns of leads (I, II, III, V1, V2, and V3 on the left; aVR, AVL, aVF, V4, V5 and V6 on the right). The computer can then select the last beat on the left side and the first beat of the right side, with automated industry standard or manual artifact rejection. A rhythm strip may be included thereby enabling visualization of virtually all features summarized by the code and score. To improve communication, this miniaturized EKG can similarly be incorporated in notes such as the official history and physical report, again driven by a cutoff score (which could be overridden by the user).
Systemic vs Local: Current vs. Longterm:
For simplicity, features and subfeatures shown herein generally have been associated with a single score—that being the score that reflects systemic impact in the preoperative context. However, as noted above, other alternatives may be indicated in other settings and within a given setting so as to reflect such issues as:
-
- Systemic and Local effects
- Current and Longterm effects, with potential subdivisions of current into preoperative, acute, intensive care, and emergency
Different forms of the present invention can be adapted to the four potential scoring combinations. However, one score is provided as the default score for the given version; e.g., “systemic/current” for the version displayed in FIG. 32 and FIGS. 26-31 , and throughout this document for preoperative assessment. Such uniform scoring can be tailored to the given form. However, one also could retain the options to enable selection of more than one score for a given item so as enable listing of systemic vs. local and current vs. longterm characteristics. This concurrent scoring may take the form of a uniform sequence such as systemic current/local current—systemic longterm/local longterm. As noted above, the default score can be changed for each entry. A preferred option is a drop-down menu. To accommodate changes because of systemic/local or current/longterm categories, this drop-down menu similarly can enable changing options (with appropriate sequences and/or coding).
The systemic and local effects, as well as the acute and chronic effects of a given condition may be recorded with separate programs with options for automated co-population of items with equivalent scores in multiple programs. Alternatively, two or more scores can be provided in a single database. Options include:
-
- Concurrent scoring of systemic and local effects of a disorder. A convention may be established wherein, if both are included, they are configured “systemic/local.”
- Concurrent scoring of current and longterm effects of a disorder. A convention may be established wherein, if both are included, they are configured “current/longterm”
- Concurrent scoring of “systemic/local” and “current/longterm.” This may be accomplished as “systemic current/local current—systemic long term/local longterm.”
The implications of this approach are delineated in Table 18. It may be particularly helpful in delineating the systemic as well as local effects of the history of present illness, i.e., the reason for surgery. Such detailed distinctions would not be necessary for most conditions. Institutions and/or individuals may determine when multiple scoring would be indicated and which components should be included.
TABLE 18 |
Examples of Concurrent Scoring Using the Proposed 0-5 Scale. |
(Systemic Current/Local Current-Systemic Longterm/Local Longterm |
Macular degeneration causing progressive loss of vision in one eye |
(wherein effect on the given organ is greater than the |
systemic effect): 2/3-2/4. |
Acute myocardial infarction (wherein the local and systemic effects |
are comparable): 4-3/4-3. |

and subsequent hormone replacement: 2/3-2/2. |

In a preferred embodiment, the default score for each included component will be provided (e.g., current systemic for the preanesthetic assessment, with a drop-down or right-click menu for selecting additional scores.
Interfacing with Other Coding Systems—Overview:
The inventive features described earlier for interfacing with diagnostic and treatment algorithms—e.g., the use of a common language, as facilitated by a conversion dictionary, to document the equivalency (or similarity) of different terms and the use of a score to relate severity—are also relevant to interfacing with other coding systems. Here we see the flexibility of the SHAPE™ system as a means of exporting inventive codes and scores or portions thereof as well as a means for incorporating codes from other systems into the systemic coding and inventive scoring introduced herein.
Potential Applications, Integrations, and Advantages of the Inventive System with Respect to Other Coding Systems:
Many of the advantages of the present system are due to its underlying structure. Whereas a program such as ICD-9 is driven by coding (and accompanying acceptable text), the present invention is driven by systematically obtained clinically relevant text, which in turn systematically generates coding and scoring on a consistent scale.
The present invention of coding and scoring—with its accompanying scorable universal language—provides the details (nature of a patient's disorders and their scored severity), classification, uniformity, and potential multi-purpose integration that are not provided by other methods. The present invention enables scored coding of conditions, lab results, responses to challenges and therapy, and outcome according to categories such as bodily system and severity of disorder/dysfunction. Moreover, it does so at the time of information entry (into clinical note, primary database, and sites of co-populaton)—not by retrospective case-by-case chart review or reliance on recollection in association with coding texts.
The potential for bidirectional information exchange afforded by the present invention enables much-needed systematizing and universalizing of the information sent to or generated by a variety of sources (many of which have been discussed above), including other coding systems. Many are included below to show the universal nature of the inventive system in accordance with Table 2:
-
- different types of visits and different types of encounters
- questionnaires
- lab testing (ordering tests, reviewing results)
- events (e.g., intraoperative occurrences such as the direct effect of surgery as well as intraoperative and postoperative effects on blood pressure, blood volume, respiratory function, etc.). These not only are scored as outcomes (FIG. 25)—which may be predicted in accordance with the preoperative SHAPE™ database, ASPIRIN™ assessment and derived indices but also as a source of new input into the database—e.g., the RESPIRATORY system may change from a SISS™=2 to a SISS™=4 because of pain-induced ventilatory compromise.
- Quality assurance and facilitated compliance with established criteria; e.g. NSQIP criteria within a given system.
- Facilitated compliance with standards of care and quality improvement measures; e.g., SCIP measures for antibiotics (based on an inventive score for infection in the “S” of ASPIRIN™.
- Accrual of data for evidence-based research
- Billing based on nature and severity of primary illness, related procedure(s) and nature and severity of comorbidities
- Other forms of co-population described above when deemed relevant to coding.
Advantages—Integrated Adherence to Required Assessments and Billing Regulations in Accordance with Quality Clinical Care: Current Regulatory Requirements for History and Physical and Coding
The application of the present invention and its methods to the perioperative period should be viewed in the context of current requirements. Prior to surgery, regulatory agencies currently require:
-
- a surgically focused history and physical exam which focuses on the nature and severity of the surgical problem—signed by the surgeon; and
- a general history and physical which includes allergies, current medications, social habits (smoking, alcohol, drugs), prior surgeries, review of bodily systems, physical examination (including heart, lungs and vital signs), and relevant laboratory testing (what is relevant is often a subject of debate that may be systematized by the inventive system).
These two components, which are not necessarily incorporated in the same note (e.g., the former may be completed by the surgeon, the latter by the patient's primary care physician), have different coding requirements; i.e., as noted above, the surgical procedure commonly is defined by a CPT code while the patient's morbidities are defined by ICD-9 codes.
Inventive Solutions: Overview
If and when a universal form of coding based on the inventive system is established, then it would be practical to either abolish the other coding systems or, perhaps more appropriately, incorporate the other system(s)'s code in the SHAPE™ data (as detailed below).
Inventive Solutions Incorporating Established Codes within the Inventive Code/Score
A preferred embodiment for uniform coding and scoring of different sources of information entails reliance on the inventive system of coding and scoring, with incorporation of the ICD code into items where an ICD-9 code currently is deemed indicated. An example is the general history and physical described above. Options are provided in Table 19.
In light of the inventor's goal to maintain consistency within the SHAPE™ database, the preferred embodiment retains sequential numbering for the level of branching (e.g., feature, subfeature, or descriptor) for which the code from the alternative source (e.g., the ICD-9 code) applies. There are several potential methods for including both the sequential code and the ICD-9 code, including:
-
- Listing the sequential code and following this with the ICD-9 code which may be designated in a variety of ways including preceding it by a dash or enclosing the ICD-9 code in parentheses (as shown in Table 19).
- Listing the sequential code and embedding the ICD-9 at the appropriate level of branching after the sequential code (again, set off by punctuation)
- Replacing the sequential code with the ICD-9 code in the appropriate cells (
FIG. 14 ) (preceded in a preferred embodiment by the appropriate number of decimal points to designate the branch level) so long as the program cites it in the corresponding cell assigned to the given item in the database.
TABLE 19 |
Examples of Options for Interfacing the Present Invention with Other Coding, e.g., ICD-9 |
1. Include terms associated with specific ICD-9 codes as hard-coded options. Selection could |
automatically include the ICD-9 code. |
2. Include hard-coded choices or screens that are consistent with categories or subcategories of the ICD- |
9 system. Selection could automatically jump to a screen wherein the relevant codes and text are listed |
and/or interface with the appropriate section of the ICD-9 program. |
3. Provide options to jump from a given item to a screen(s) with potentially applicable ICD-9 codes and |
associated terms. |
4. Adapt Conversion Dictionary (described in text) to list text and coding synonyms for SHAPE ™ vs |
ICD-9 and enable jumps between them. |
5. Click of ICD-9 code, prompting reverse jump to SHAPE ™ (Less advantageous because this |
eliminates many of the advantages of the inventive system, including time of entry coding and scoring, |
storage in accordance with inventive branched-chain logic). |
The behind the scenes conversion and integration may be accomplished in a variety of ways including:
-
- prescribed item-by-item code incorporation
- prescribed item-by-item code conversion
- prescribed item-by-item integrative index for identical text
- based upon a conversion dictionary which establishes equivalency of different texts
- user determination of text matching
- establishing programs based upon a universal language (text, code, score) so as to minimize the need for specific conversions for different means of data entry and recording
Inventive Solutions Incorporating the Inventive Code/Score in Established Code(s)
If one is performing a surgically focused history and physical or seeing a patient for a focused examination of a specific disorder, then—until the proposed uniform means of coding and scoring described herein is universally adopted (if and when)—it may be more practical to include such information from SHAPE™ in the other (e.g., ICD-9 or CPT) code. While inclusion of the entire SHAPE™ code (as described above) would provide the most complete information and coding, a reasonable compromise would be to simply include a portion of the code and the system or feature score. Adaptation for procedures may be as simple as modifying the CPT code with the SOCU™ score of the inventive system. This enables the code to provide an indication of risk/invasiveness that otherwise might not be evident. Likewise, the codes for anesthesia relative value units can be annotated similarly.
This incorporation of information from the inventive system may be accomplished for classification systems such as the ICD-9 codes and CPT code in a number of ways, including:
-
- modifying the ICD-9 code so that it lists the system-specific score (e.g., SISS™, SICU™) as may be accomplished by “$#” wherein # is the 1-5 (or 0-5 or other established range) score.
- assigning all or part of the coding for branch logic to the ICD-9 code
- One may export the system code so as to help in categorizing for quality assurance and research purposes. Inclusion of more distal branches will provide greater specificity. Simply providing this level of documentation could unify coding systems with respect to a common logic for organization and a common means of assessing severity.
The system code may be generated from a common list of systems or via computer by creep seek typing which generates the code for the system in addition to its name. Subsystem code may be generated as per above, with the potential to facilitate this with a dropdown menu when a system is selected electronically. Scoring can be generated by the means described for scoring above, with the potential to generate the score electronically if the selection is generated electronically as may be enabled by arrays such as those in Tables 10 and 10b, as well as FIGS. 26-32 .
The actual steps may entail a variety of potential means, including:
-
- simply copying the relevant information from SHAPE™ (e.g., relevant portions of code and score, by hand or electronically) to the ICD-9 code. Equivalence of different textual descriptions may be mediated via the conversion dictionary described above
- providing automated options for selecting a score when assigning the ICD-9 code
The first of these two options is preferable because then the score is assigned at time of entry of the clinical assessment, without the need to review the record to identify the information needed for such coding and scoring. The advantages of incorporating established codes within the inventive code may be appreciated in the following example: a patient with advanced diabetes and associated atherosclerotic cardiovascular disease sees a physician because of a nonhealing foot infection with evidence of systemic infection. Since this involves multiple systems, it is cumbersome, at best, to capture the multiple presenting problems and relevant comorbidities with current coding. Incorporating the inventive codes and scores likewise could be cumbersome. However, generating the inventive codes and scores (for each system as it relates to the patient's status) as a basic component of the history and physical examination—with incorporation of the established billing codes as deemed indicated—should be far more efficient (and less prone to inadvertent, arguable, or deliberate misrepresentation). Such misrepresentation is a costly process for Medicare and private insurers and for those obligated to justify that they were in compliance.
Alternatively, one simply could add an ASA score to a code such as the ICD-9. However, we believe that is best accomplished with automated conversions described above or template-driven assignments, where there are provisions in the template for any or all of the following:
-
- score assigned in SHAPE™ or in a comparable program based on the information disclosed herein
- system code in SHAPE™ or in a comparable program based on the information disclosed herein
- more complete code assigned in SHAPE™ with or without the score
The aforementioned inventive options for coding and scoring will enable storage in a common database, with the realization that certain cells may not include the full extent of branch-chain logic (e.g., by branching only to the subsystem level). This should provide far greater universality than simply storing according to an ICD-9 code or a CPT code.
Inventive Solutions Application to the Anesthesia Preoperative Note:
The typical preoperative assessment by an anesthesiologist, the initial focus of many of the embodiments described herein, contains elements of both a specific surgically focused and general history and physical examination. The surgical problem, which may be described at the beginning of the note, as per common practice, in a “history of present illness” commonly referred to as “HPI,” may affect multiple systems as is the case for multiple system disorder.
For example, a thyroid abnormality requiring surgery may cause: difficulty swallowing, shortness of breath when lying flat, hoarseness secondary to recurrent laryngeal nerve involvement, hypertension, an abnormal cardiac rhythm (e.g., atrial fibrillation), weight loss, and anxiety. The interaction of the inventive code/score and established codes may be depend on the configuration of the actual note—are the consequences of the abnormal thyroid listed under HPI, under Endocrine/Thyroid, or under the other affected systems. A preferred embodiment entails partial co-population of the relevant sections, with details provided upon jumps to the affected systems/subsystems/feature categories. With such an arrangement, the incorporation of other codes into the inventive system likely would be more efficient that the exportation of inventive codes and scores to means for ICD-9 and CPT coding. Clearly, if the latter is employed, the surgical procedure itself (its system code and its system-specific SICU™ score or overall SOCU™ score) could be exported to the other means of coding (e.g., CPT code). However, simply doing that alone would sacrifice potential useful data in that it would not take into account the multiple-system effects of many surgeries that are delineable with the inventive SICU™ score. Again, the inventive system offers the advantage of coding at the time of information entry as opposed to having to match a code to a diagnosis by retrospective review.
This is in contrast to the information provided by the inventive text and its code: nature of the disorder, signs and symptoms, uniformly scored severity of the signs and symptoms (systemic impact and local impact if deemed indicated), and their response to therapy.
Advantages of the Present Invention:
The integrative function of the inventive program and the associated inventive indices provide for integrated assessments of disorders and challenges and interventions that are not attainable with other programs (Table 2). Among the components unique to the present invention is the score-driven ability to:
-
- launch general laboratory testing and specialized testing and score their results;
- direct score-driven triaging to an anesthesiologist and score anesthesiologist's findings;
- generate and justify consultation by the patient's PCP or a specialist and score those findings
- allow for typing free-text which is coded and scored (as described herein)
- maintain a database well-suited for displaying, reporting, analyzing, co-populating, importing and exporting information
- grade significance from different perspectives, including systemic vs. local, acute (perioperative) vs. longterm
- generate score-driven records (e.g., wallet card)
- accelerate the identification of variables and outcomes of QA programs (e.g., NSQIP) and provide a common score-based language for identifying and coding common factors.
Many of the advantages of the present system are due to its underlying structure. Whereas a program such as ICD-9 is driven by coding (and accompanying acceptable text), the inventive system is driven by systematically obtained clinically relevant text, which in turn systematically generates coding and scoring on a consistent scale. Whereas to the inventor it appears that the inventive system should replace a complex system such as ICD-9, it is more realistic to assume that the systems could be integrated with matching of terms analogous to that for Importing and Exporting. Table 19 lists ways in which SHAPE™ could be interfaced with the coding of ICD-9.
The widely used CPT (Current Procedural Terminology) code provides a 5-digit code for procedures. These are grouped as “Evaluation and Management, Anesthesiology, Surgery, Radiology, Pathology and Laboratory, Medicine. As is the case for ICD codes, the CPT coding system lacks the score-based coding that typifies the inventive system. As noted in Table 10b, surgeries impact on multiple systems and thus may be not be amenable to the same branched-chain logic as medical conditions. Adaptation for procedures may be as simple as modifying the CPT code with the SOCU™ score of the inventive system. This enables the code to provide an indication of risk/invasiveness that otherwise might not be evident. Likewise, the codes for anesthesia relative value units can be annotated similarly.
Thus, the present invention provides the basis for detailed scored coding based on branched-chain logic with the potential for: 1) incorporation of an existing code such as ICD-9 and CPT; 2) incorporation of the inventive score in those existing codes. Likewise, there can be integration at specific levels between the inventive system and existing programs that assign codes to health care information. Such codes could be augmented with the inventive scores (e.g., SISS™, SOCU™ and/or SICU™) and other aspects of the inventive system, including: amending coding in accordance with the inventive coding and scoring for branched-chain logic; adapting inventive means for categorizing and scoring type-ins and imports; providing for score-driven displays, scripts, exports, and data transmission and storage.
Overall Database
The overall database can be constructed in a variety of ways, examples of which are shown in FIGS. 13 , 14 and 16. The coding of this embodiment is in accordance with the branched-chain logic shown in FIGS. 26-31 . The unpopulated database may include all potential entries (positive as well as negative, likely as well as unlikely) and allot space for imports and type-ins (as shown in this arrangement) or it may be configured so that only the selected (positive) entries are entered. The “$” columns enable each scored item to be entered into the appropriate column; the proposed 0-5 scale is shown in this figure. Although potentially requiring more storage space, it may be preferable to assign separate cells to each potential score for a given item.
Other optional aspects of the database include management of potential type-ins and imports. Established items should be hard-coded into the database. For other items, the database can be “expanded” to absorb new entries or cells, with rows and/or columns reserved for type-ins or imports related to a given hard-coded item. The “reservation” could include all or part of the code and default score (with the potential for customization according to the source of import as with a letter suffix). If the potential source is an established source of import, then the actual text may accompany the code in the reserved cell(s) comparable to the arrangement for hard-coded choices. These provisions for add-ins and type-ins can be in columns to the right of the standard hard-coded choices or can be established for entry immediately below the relevant hard-coded choice.
A separate column can designate the source of the information (e.g., current H&P, surgeon's note . . . ). Another column can designate as to sites of co-population and sites of export, in coordination with relationships defined in the conversion dictionary and/or interactive index.
Even if it co-populates multiple regions, a given feature, subfeature or descriptor maintains its level-specific code throughout the database; however, if it co-populates different feature categories, subsystems or systems, the proximal portion of its code will differ.
In embodiments where scoring is based solely on scores assigned to features and subfeatures, it is obvious that scores assigned to more proximal branch levels are based upon the scores associated with the more distal features and subfeatures. Conversely, in embodiments where the level of hard-coded scoring is not limited to features and subfeatures, then it may be important to distinguish between hard-coded and derived scores (e.g., by assigning to different columns, annotating with a letter code, etc).
Additionally, other scoring systems may be employed within the scope and spirit of this invention. This may be achieved by converting other quantitative or qualitative measures to the 1-5 or 0-5 scores described above. Alternatively, an alternative graded range may be utilized (e.g., 0=none, 1=mild, 2=moderate, 3=severe) so long as consistency of scoring among components is maintained.
Whereas the detailed clinical information within the SHAPE™ database would be accessible for integration with a hospital's data network via established links based upon criteria such as name, birthdate and medical record number, inclusion of all data on each patient in a common database likely would be cumbersome. The present invention's consolidation of patient data enables efficient integration of vital data with links to sources of greater detail. FIG. 13 shows how the addition of approximately 15-30 columns increases the robustness of the clinical information in the database from the common listing of demographic data, costs and established codes (e.g., codes for International Classification of Disease (ICD-9) and Current Procedural Terminology (CPT) classifications)—the limitations of which are discussed later in this text—to body system by body system delineation of medical conditions (nature and severity) and, if deemed indicated, comparable delineation of surgical impact, risk indicators and integrated assessments. This provides ready access to such information for functions such as billing, resource allocation, predicting personnel and time requirements, quality assurance, auditing and research. The coding and scoring described herein enable simple linking to the details within the inclusive SHAPE™ database; e.g., more specifics as to the nature of a patient's class 3 disorder(s) of the Cardiac system as summarized at the end of the sample note (FIG. 4 ) and enabled by the ASPIRIN™ display (FIGS. 6 and 7 ). The optional linking to the detailed information—as may be indicated for detailed billing, quality assurance (e.g., to confirm adherence to diagnostic and treatment algorithms), medicolegal documentation and research—is mediated by a single cell (e.g., a patient's score for the Cardiac system) in the integrated hospital database, as opposed to a complex array of codes (e.g., ICD-9) which in and of themselves do not indicate disease severity and require a dictionary to identify the nature of the given disorder. To limit the size of the integrated database long-term, a patient's surgical procedure(s) could simply be consolidated according to its overall severity with an inventive code that integrates the risk/invasiveness score and the CPT code, with a link from that single cell to the itemization provided by the SICU™ score when more details are needed about a specific procedure.
The Sample Codes for Relevant Healthcare Providers and Information Sources are as follows:
-
- A=Anesthesiologist
- C=Consultant
- P=PCP
- S=Surgeon
- H=Automatically generated by History and Physical
- L=Automatically (electronically) entered from Laboratory (but not yet reviewed by a healthcare provider
- Q=Questionnaire
The codes may be generated simply by clicking in the cell or item (after electronic sign-in to the computer) which, in turn, would automatically identify and timestamp the entries of the given healthcare provider.
If the patient has active hepatic (liver) disease (e.g., SISS 4 or 5 for Hepatic system), would likely obtain liver function tests periodically and prior to virtually any challenge. If patient has history of prior liver disease, then decision to obtain liver function tests would depend on combination of the nature and severity of the condition (SISS™ score) and hepatic risk/invasiveness of the planned procedure (e.g., SISS™=3+SICU™=3 provides much greater indication than either score alone). As for other aspects of the inventive program, decisions may be overridden and institutions can establish different cutoffs (without compromising the inter-institutional recording and storage of data entry since that may be entered in accordance with established clinical guidelines and is not influenced by what one subsequently does with the entries).
Code(s) for source(s) of request to address the issue entered to the left of the “/” (based on coding described with respect to FIG. 17 ); code(s) for healthcare provider(s) generating the order to the right of the “/.” As per FIG. 17 , the same healthcare often would be designated before and after the “/.” A “/” (or an entry to the left of the blank) may not be needed, unless the healthcare provider who identifies the need to make a decision defers the decision to a colleague (e.g., to the cardiologist).
Uniform terminology is provided in left-hand column for simplicity. However, by clicking on a cell, one can discern medication-specific or device-specific scoring graduations that—while remaining compatible with the more general terms—provide more relevant information. For example:
-
- *=Columns for ICD9 and CPT codes included herein for completeness;
- Y=usually yes;
- +=maybe;
- Y=likely indicated;
- ±=borderline; numbers in cells indicate strength of indication (0 to 5 scale) as per
FIG. 16 ; and - X=not applicable because no surgical procedure cited in ASPIRIN™ score.
Looking toward the future of the present system, the following features will be primary sources for future development:
-
- progressive coding with a fixed variable component
- consistent coding of any or all of the following:
- system-specific ASA score, system-specific assessments of physical status, overall physical status, system-specific scoring of surgical impact, scoring of overall surgical impact
- risk indicators
- indications for testing
- factors affecting ventilation, factors likely to affect intubation
- outcome
- monitoring indices
- criteria for triaging
- quality assurance
- establishing a network of integrative indices based simply on scored assessment of data on routine history and physical and laboratory testing
- use of a conversion dictionary and integration of different features to facilitate textual descriptions, coding that enables relative searching and retrieval, and effective scoring used to interact with other databases
- means to integrate data from other databases
Although specific body systems are referred throughout this disclosure in an effort to describe preferred embodiments, those skilled in the art will appreciate the present invention may be applied to a variety of body systems without departing from the spirit of the present invention.
While the preferred embodiments, indices and acronyms have been shown and described, it will be understood that there is no intent to limit the invention by such disclosure, but rather, is intended to cover all modifications and alternate constructions falling within the spirit and scope of the invention. It also should be noted that while the range of scores shown for the embodiments disclosed herein parallel the range for the ASA score, it would be within the spirit of this invention to utilize an alternative range of gradations so long as consistency was maintained among the different components of the SHAPE™ database and/or alternative components
